Pumpkin blocks, watermelon blocks, and carved pumpkin blocks are not affected by slime blocks.

Summary:
When a Slime Block is moved by a piston, adjacent Pumpkin, Melon, or Carved Pumpkin blocks do not move along with it.

Expected Result:
Pumpkin, Melon, and Carved Pumpkin blocks should move together with the Slime Block, just like other movable blocks attached to it.

Observed Result:
Only the Slime Block moves, while the Pumpkin, Melon, or Carved Pumpkin blocks remain stationary.

Steps to Reproduce:

1. Place a Sticky Piston.

2. Place a Slime Block in front of it.

3. Attach a Pumpkin, Melon, or Carved Pumpkin block to any side of the Slime Block.

4. Power the piston.

Result:
The Slime Block moves, but the attached block (Pumpkin, Melon, or Carved Pumpkin) does not.

Version:
Minecraft Bedrock Edition 1.21.114

Additional Notes:
These blocks might be incorrectly flagged as “non-movable” or “non-stickable” in the block behavior data, preventing them from interacting properly with Slime Blocks.
