This mod will overhaul the creepy crawlies like silverfish and endermites by expanding the families. These new grubs and other creatures will infest different blocks based on biomes.
Grub: grubs can be found in infested grasblocks that they will feed on turning it into normal dirt when dug out they will try to burry themselves in or you can capture them or kill them.
Bloodworm: spawns in infested mud in mangrove swamps and will bite the player when their home is demolished
Millipedes: millipedes can be found in the jungles eating away leaves and other plants and can be found in infested jungle logs hiding away. These mobs are friendly and can be used for composting.
Deep ocean isopod: these creepy isopods can be found in cold ocean at the sea floor feeding on sea grass. They attack drowned as they normally eat decaying carcasses of Dead Sea life.
Bobbit worm: bobbit worms can be found in coral reefs in infested sand or gravel and will attack anything that swims over it they can be killed for their mandibles.
Antlion: antlions lurk in the badlands and will create sinkholes when you walk over them biting you.
Nethermites: these creatures will pop out of basalt blocks when mined or provoked attacking the player
Soulverfish live in infested soul sand and will shoot out a silky substance to slow down the player. They can be killed for soul silk
These are all weird concepts for creatures all the above accept for the nethermite and soulverfish are based on real life creatures!
