Jellybean Guide:

Jellybeans are the core mechanic of A Boy and His Blob. Each bean transforms the blob into a different object, providing unique abilities to solve puzzles and traverse the environment. Here’s a breakdown of each jellybean, listed in the order they appear in the selection menu:

• Licorice: (Starting Quantity: 72) Turns the blob into a ladder. Essential for reaching high places.

• Strawberry: (Starting Quantity: 15) Turns the blob into a bridge. Allows you to cross gaps.

• Coconut: (Starting Quantity: 6) Turns the blob into a coconut. Can be thrown, but its usefulness is limited.

• Cola: (Starting Quantity: 18) Turns the blob into a bubble. Allows you to traverse underwater without drowning.

• Cinnamon: (Starting Quantity: 24) Turns the blob into a blowtorch. Used to burn obstacles.

• Apple: (Starting Quantity: 12) Turns the blob into a jack. Used to bump or dislodge objects.

• Vanilla: (Starting Quantity: 30) Turns the blob into an umbrella. Protects you from falling objects and slows your descent.

• Tangerine: (Starting Quantity: 42) Turns the blob into a trampoline. Bounces you to higher areas.

• Root Beer: (Starting Quantity: 6) Turns the blob into a rocket. Takes you to Blobolonia (another planet).

• Honey: (Starting Quantity: 52) Turns the blob into a hummingbird. Allows the blob to follow you more easily in some situations.

• Ketchup: (Starting Quantity: 6) Makes the blob appear wherever you throw it (teleportation).

• Punch: (Starting Quantity: 54) Turns the blob into a hole. Creates a pit to fall through.

• Orange: (Starting Quantity: 0, acquired later) Turns the blob into a vitamin blaster. Shoots vitamins as projectiles.

• Lime: (Starting Quantity: 0, acquired later) Turns the blob into a key. Unlocks doors.

Walkthrough: Treasure Hunting

This section guides you through collecting all the treasure before venturing to Blobolonia.

1. Starting Out: Go two screens to the right. Enter the subway by pressing down. Go one screen right. Use the Punch Jellybean to create a hole and fall through.

2. Treasure 1: Go one screen left. Use the Licorice Jellybean near the ledge and grab the treasure.

3. Treasure 2: Go two screens right. Use the Punch Jellybean near the left side of the screen to avoid falling on an enemy below. Call the blob, but don’t stand under him, or you’ll fall through another hole. Use the Vanilla Jellybean to create an umbrella and walk under the “worm” to get the treasure.

4. Treasures 3 & 4: Go three screens right and fall down the hole (umbrella required!). Get the treasure to the right. Use the Cinnamon Jellybean to burn the spider web and then continue right past falling rocks (umbrella recommended). Then use the Strawberry Jellybean to make a bridge to get across the gap to the treasure.

5. Treasure 5: Call the blob back and fall down the hole. Go two screens to the right and drop down. Use the Tangerine Jellybean about 2/3 of the way across the screen to reach the diamond.

6. Treasure 6: Use the Punch Jellybean to the left to drop onto the left ledge. Go left and get the treasure guarded by the “worm”.

7. Treasure 7: Have the blob fall down and stand under him to fall through. Go left one screen and use 3 Licorice Jellybeans to reach another treasure. Place the ladders inside the platform.

8. Treasures 8, 9, & 10: Drop down the ledges one by one. Use a Punch Jellybean on the left side of the screen. Go one screen left and use the Tangerine Jellybean in the middle. Bounce to the top and fall to the left. Use the Honey Jellybean to help the blob follow you. Go one screen left, drop down a ledge, and grab the treasure. Have the blob drop on you (in hole form) to drop down again for another treasure. Stand under the blob AGAIN and fall down the hole to get ANOTHER treasure on the right.

9. Treasure 11 & Jellybean Bags: Use the Vanilla Jellybean and go left. Fall off the ledge to the left and continue left to find a jellybean bag (and treasure).

10. Underwater Section: Go one screen right and fall down. Go one screen left and fall, avoiding the “worm”. You’ll reach water. Use the Cola Jellybean and enter the bubble. Go two screens right, then down through the opening. Go left first to grab a treasure. Then go right, staying near the bottom to avoid the spiked ceiling.

11. Treasure 12: Go one screen down. Carefully navigate the spikes to get the treasure.

12. Treasures 13-18: Go up one screen and one screen to the right. There are THREE treasures on this screen. The next screen to the right also has THREE treasures. Return to the opening and head back to the ledge on the left.

13. Escape the Sewer: Use a Licorice Jellybean to go up and a Strawberry Jellybean to cross the gap. Go right. Use a Tangerine Jellybean VERY close to the ledge above and land on the left ledge near the ceiling. Go one screen left and use a Ketchup Jellybean to teleport. Use a Licorice Jellybean, go one screen right (you can’t use the ladder on the same screen you climbed up), then use another Licorice Jellybean. Go one screen to the left and use a Tangerine Jellybean to get the last treasure floating in the ceiling.

14. Final Preparations: Use a Licorice Jellybean to climb up. Go to the right and use another Licorice Jellybean to climb up another ledge. Climb the ledges to the left until you reach the top (two blue ledges; stand on the higher one). Go left and grab the Jellybean bag (containing the Orange and Lime Jellybeans). Return right, using the Strawberry Jellybean for the gap. Use the Apple Jellybean on the hole in the ceiling to remove the sewer lid. Use the Licorice Jellybean to climb out. Go to the right until you reach the store.

15. The Store: The store sells vitamins, which are ammo for the Orange Jellybean’s vitamin blaster.

Walkthrough: After Treasure Hunting (Blobolonia)

After collecting all the treasure, use the Root Beer Jellybean to reach Blobolonia.

1. Marshmallow Mayhem: Use the Orange Jellybean to equip the blaster. Navigate the bouncing marshmallows. Shooting them alters their pattern. Two screens to the right is the first set of marshmallow obstacles. Continue two more screens past more marshmallows, finding an opening and just running across without stopping. If you timed it right, you will make it.

2. Cherry Bombardment: The next screen has cherries. If they hit the ground (or you), you die. Shoot the lowest cherries first with Vitamin B (lowest arc). Repeat for the next two screens.

3. Popcorn Panic: Go four screens to the right. You’re now in a cornfield dodging popcorn. You can shoot them, but it’s often better to avoid them.

   • Alternative (potentially cheating) Method: Use the Coconut Jellybean and gain momentum by walking back and forth. Throw the coconut to clear the popcorn at the start of the field. Repeat to clear the entire field.

4. Candy Factory: Enter the building to the right. Place the blob slightly left of center and give him a Tangerine Jellybean. Bounce up to the floating candy cane. Go to the right and turn off the marshmallow-dropping machine. Use the Ketchup Jellybean to spawn the blob and give him a Vanilla Jellybean. Fall off the ledge to the right (repeat this factory puzzle one more time).

5. Cave Exploration: Go to the right and enter the cave. Navigate two screens of randomly appearing teeth. Use the Punch Jellybean in the middle to drop down. Go right to turn off the Hershey’s Kisses machine. Use the Tangerine Jellybean below the pot to bounce back up to the right, then use the Honey Jellybean to have the blob follow you.

6. Candy Cave: Go two screens to the right, past more teeth. Go three screens to the right, past the gingerbread men. Use the Lime Jellybean to unlock the door.

Final “Boss”:

After unlocking the door, the blob is imprisoned by a grey creature. Whistle for the blob to revert him from key form. “Equip” the Apple Jellybean and walk back and forth to gain momentum. Throw the jellybean while moving. The jack should enter the blob’s mouth. This causes the blob to push against the imprisoning jar, spilling vitamins on the grey creature, defeating it and finishing the game.

The ending shows the end of the story and an ending screen.
