an inchworm, they inch along the dirt and sometimes crawls up plants. they drop: inchworm skin and inchworm head.

maggots, you can take pick them up and grow them into flies which you can ride with a saddle, but it needs to be fed or else you can't fly on it,

earthworms, you can find their holes where you can find cool things and an earthworm or two.

earwigs, i don't have many ideas, but they can drop: earwig legs that you can cook and eat and earwig parts.

BONUS! an antman figure in an ant hill as an easter egg.
