The Can't Tuck Snail is a snail who works at the corner and is one of Carl's employees. Not much is known about him. All we know is that he is fat enough to not fit in his shell and yells, "I can't tuck! I can't tuck!", when there is a Tuck-and-Roll drill. In a post-credits scene, he is seen to have managed to tuck in his shell, but couldn't get out.
- He is voiced by David Soren, the director of Turbo.
