Dolt Cave Addon Mod extends Alex’s Caves Neo with new block interactions, mob behaviors, and cross-mod content. It ports specific cave tweaks over from Dolt Mod How. You get smarter submarine mechanics, renewable muck, and longer-lasting nuclear fuel. The mod also connects with other popular mods like Environmental, Farmer’s Delight, and Woodworks to bring new Slabfish types and wooden furniture.

Features:
- New Slabfish Variants: Adds Environmental Slabfish types for every biome in Alex’s Caves.
- Smarter Submarines: Player-built submarines match the rust and wax level of the copper blocks used to build them. If Caverns & Chasms is installed, destroyed submarines drop copper ingots matching that same state, and repairing a submarine plays the copper golem repair sound.
- Renewable Muck: Mud blocks placed under Y=-16 inside an Abyssal Chasm biome with 20 solid water blocks above them slowly turn into muck blocks.
- Stronger Uranium Rods: One uranium rod now smelts 20 stacks of items in a nuclear furnace instead of just 1 stack.
- Chest Protection: Vallumraptors fail to steal items when they try to open chests guarded by a Spawn octopus.
- Woodworks and Farmer’s Delight Blocks: Adds chests, trapped chests, bookshelves, chiseled bookshelves, ladders, boards, beehives, and cabinets made from Pewen and Thornwood.
- Adds a 3×3 Crate of Pine Nuts storage block and a Pile of Ancient Leaves block.
- Stops acid from corroding copper blocks.
- Lets you eat Biome Treats even when your hunger bar is not empty.
- Changes Marine Snow so it revives all modded corals and duplicates ping pong sponges instead of vanilla sponges.
- Limits Biome Crucibles so they only replace stone, dirt, and sand.
- Lets you use an axe to scrape rust off scrap metal from Alex’s Caves.
- Allows cycads to be planted on sand blocks.
