What Is This Mod?
Not So Shrimple adds dangerous crustacean-themed creatures, animated weapons, upgrade items, and strange aquatic encounters to your world.
This port keeps the spirit of the original mod while adapting it for Minecraft 1.20.1, Forge 47+, and GeckoLib 4.
Creatures
Crayfish

Crayfish are hostile semi-aquatic mobs with multiple variants.
They are tough, aggressive, and come with different visual styles depending on how they are summoned.
In this port, crayfish no longer spawn naturally. Instead, they are summoned using a Bucket of Bait.
Crayfish variants include:
- Normal variants from regular water
- Ice variants from cold biome water
- Blood/fire variants from Nether lava
- Rare special variants
Maneater

The Maneater is a hostile shell creature found near shipwrecks.
Its spawning has been reworked for this port so encounters feel more controlled and less spammy.
Maneaters can appear near:
- Shipwrecks
- Beached shipwrecks
Spawn rates are intentionally limited, making each encounter feel more deliberate.
Bucket of Bait
The Bucket of Bait is the new way to summon crayfish.
Craft it using a bucket and raw fish, then throw it into water or lava.
After a short delay, it has a configurable chance to summon a crayfish nearby.
Summoning rules:
- Throw into water to summon normal or ice crayfish
- Throw into cold biome water for ice variants
- Throw into Nether lava for blood/fire variants
- The summoned crayfish appears nearby, not directly on top of the bait
- Summoned crayfish briefly glow so they are easier to find
River-Prawn Greatclaw
The River-Prawn Greatclaw is a custom animated GeckoLib weapon.
It features:
- Heavy melee damage
- Durability-based use
- A ground-slam attack
- A visual block-wave effect
- Area damage that scales with fall speed
The harder you fall, the wider the slam impact becomes.
Items
The mod also includes:
- Raw Prawn
- Cooked Prawn
- Smithing Stones
- Somber Stones
- Purging Stone
- Crayfish and Maneater spawn eggs
Smithing and Somber Stones can upgrade supported equipment, with configurable caps and tag-based blacklist/whitelist support.
Coming In A Future Update
A new mob is already being prepared for a future update.
It is not available in the current release yet, but development has already started.
More details will be revealed once the creature is closer to release.
