A larva hatches from an egg if it eats enough it will mature if it eats more it plops on the ground and dies then a baby metroid appears out of it and then it eats and when its finnaly done eating it might become the metroid queen and lay an egg then it repeats

Alright here we go

So your saying the babies went cute because of hatching?

Well I'll first draw a matured metroid

Oh you wanna see a baby metroid
