If shears are used on them, the carved pumpkin will come off. "Melts" (Takes damage) in savanna, desert, badland, and nether biomes. If it falls in water, fire, or lava, it will melt. If you use a splash potion of fire resistance on it, it will not take damage due to melting until the potion effect runs out.

The strider only spawns in the nether, and is found walking on lava pools. When killed, drops string. With a saddle the player can ride on a strider, but to be able to control it, you will need a warped fungus on a stick. The player can ride it on land, but will get cold, and its walking speed will decrease. If the strider goes into water, or rain, it will take 1/2 a heart of damage every .5 of a second. To breed striders, the player needs to feed the striders warped fungus.

Pufferfish
The pufferfish is the only passive mob that does damage. The only reason that it is a passive mob is that in never tries to hurt the target. If a player gets too close, and is inflicted with poison damage via the pufferfish, the pufferfish will never become hostile. Pufferfish are found in ocean biomes, and when killed, they drop one pufferfish, and have a chance of dropping bones in Bedrock, and bone meal in Java. If a pufferfish is clicked on with a bucket, or a bucket of water, it will become a bucket of pufferfish. If the bucket is ever emptied, the pufferfish spawned by it cannot despawn.
