I'm making alternate more realistic designs of Kirby characters. I'm working on a version of Escargoon the "snail" here.[![Escargoon snail][1]][1] Due to his movement in the Kirby anime resembling more of a shuffle I've given my alternate version of him tiny legs sort of like a mole lizards. His movement is also fast. Not slimy looking. Not snail like. So I gave him a more serpentine tail design to realistically enable faster movement. The shell is also made larger in my alternate version.

My issue here is with the shell. I have tried to research how snails get everything inside the shell. I know they're squishy, but the part out of the shell looks too big to go in. All the diagrams I've looked at show the shell stuffed with organs with no hollow area for the rest of it when it needs to go in. (Though the serpentine tail would probably be to big to fit either way, so only the front part would have to fit in for my redesign.)[![snail structure][2]][2]

So I either need an explanation of how they fit that I can understand, or an alternate reason for a snail-like shell to be on a creature.
