Caterpillar puppet WIP

I wanna make this one into a stop-motion puppet
it’s made of pieces of a kitchen sponge and a tie from a loaf of bread i brought back from Japan
one of a kind, baby (apart from in japan)
i just remember seeing it and thinking it looked like the perfect little caterpillar face
little eyes and a mouth for munching leaves and a sort of bow at the top that looks like antennae
i’m not sure how to thread wire / an armature into the sponge though.. i might have to buy some Test Sponges and try to figure it out
