Shell Spiffy is a magazine seen in the episode Shell Shocked. Gary reads this magazine and probably dreams of having one of their expensive shells, even though it may be a magazine for fancy snails. In the cover, there is a purple snail with a pink shell that has a diamond on it. SpongeBob thought their prices were outrageous. In the book, Gary's old shell had lots of new features and cost $95,95.95 or more.
The magazine has a blue cover with a female snail on it. Over the snail, it says Shell Spiffy in red letters.
- The German title for the magazine is Das schicke Schneckenhaus, which means The Fancy Snail Shell.
- The sticky tabs in the book were from Gary, who wanted the shell.
