FunnyBlock
by Springirl
FunnyBlock, a NeoForge decoration mod for 1.21.10, adds a set of joke blocks with unusual in-world behavior.
What it does
Some of the added blocks are meant to be placed in creative mode and behave oddly: one spawns rabbits, one explodes about three seconds after being set off, and another explodes 60 ticks after a fireball or flint and steel hits it. A sponge block with stronger absorbing behavior is included, and a block made from rotten flesh is among the additions. The mod is a random-block collection in the spirit of many small decoration mods.
FunnyBlock runs on client and server, so the server and every player need it. Files are published for NeoForge only, for 1.21.10, with 1.0.1 as the latest file dated 2026-03-10. The mod was first published on 2026-02-18. The code is public, and the mod is All rights reserved, so it is not open source.
Key features
Creative-mode blocks
Some added blocks are intended for creative-mode building and play rather than survival crafting.
Rabbit-spawning block
One block spawns rabbits when it is placed or activated, so it can be used as a joke in builds.
Delayed explosion
A block explodes 60 ticks after it is triggered, giving a short countdown before the blast.
Fire-triggered explosion
A block set off by a fireball or by flint and steel explodes 60 ticks later, giving a short countdown before the blast.
Stronger sponge
A sponge block with stronger absorbing behavior than vanilla sponges is added for soaking up liquids.
Rotten flesh block
A block crafted from rotten flesh is added as a decorative and novelty item.

Use cases
Pranks on a server
Server owners and players can place the rabbit and explosive blocks in shared builds as pranks, since every player on the server needs the mod to see them.
Creative builds
Builders use the creative-mode blocks to add unusual decoration to maps and showcase worlds.
Who it’s for: The mod suits players who want random, joke-style blocks in a creative or multiplayer world. Server owners who run a shared build area can add it for the same effect.
