I poked around some online examples and tutorials.
This snail was super cute and ended up being my inspiration! Can’t get any cuter.
And then this was a nice and straight-forward tutorial for making the spiral shell, which I stuck on top of the snail.

He’s a little lop-sided and one-eyed, and after all, that shell on his back looks kind of unappetizing, but that’s what I have so far.
This is the snail that goes with the animation I’m making with one of the fifth-grade classes at Wolf Meadow, who are doing a great job animating so far. Yes, we have already started animating – can’t believe it’s gone so fast!
