Hey! This is basically the first mod I've ever made, so I kept it simple. This mod only adds 1 block - the puffer block! The main functionality is that it inflicts poison whenever stood on (can be negated by crouching.) Enjoy!
- adds the puffer block
- crafted with 4 pufferfish
- can be de-crafted into 4 pufferfish
- can be rotated
- inflicts poison when stepped on - negated by crouching
- carrots and golden carrots can be fed to it
- custom sounds for placing, breaking, hitting, and walking on it
- can be found in the Building Blocks and Functional Blocks tab
The original pufferfish burp sound effect is from this video.
