I'm not aware of many famous snails. Gee Geronimo, as far as I know, may be the only one. Back in the 1970s, the Guinness Book of Records declared him to be the world's biggest snail. His owner was Christopher Hudson. Gee Geronimo died in 1976.

Hudson was apparently more in love with his snails than he was with his wife.
