Cockroach Mod
by SirPandivian
Cockroach Mod adds a cockroach mob that spawns, breeds from rotten flesh and comes with a fly swatter tool for hunting it.
What it does
The mod introduces a cockroach entity and its baby form. Players can feed rotten flesh to cockroaches to breed them, and the mob is described as small, fast and hard to hit, which makes it a short challenge in ordinary survival play. Cockroaches are not described as spawning in any particular biome, and spawning is noted as planned for a later update.
A fly swatter tool is added alongside the mob. It is intended as the weapon against cockroaches, and the author states that spawning rules and a stronger damage value for the swatter are planned. The mod is Forge-only, runs on the 1.20.1 game version, and is released under All rights reserved, so it is not open source. Source code and an issue tracker are linked publicly. Cockroach Mod runs on client and server, so the server and every player need it.

Use cases
Adding a pest challenge
A survival world gains a small mob that players must chase down, using the swatter to deal with the breeding stock.
Who it’s for: Players on Forge 1.20.1 who want a small, simple mob and a matching tool added to survival or multiplayer play. Server owners who want the mod on both sides will also find it straightforward.
How it compares
Alex's Rotten Flesh Armor is a Forge-only mod for 1.20.1 that also uses rotten flesh, with client and server environment and All rights reserved as its license, so it is not open source. Rotten Flesh Smelt To Leather targets Fabric, Forge and NeoForge across 1.17.1 – 26.2 with the same client and server environment. Smelted Flesh is Forge-only for 1.20.1, runs server-side only and is MIT licensed, so players can join without installing it.
