In "Fungus Among Us," it is a brown bag with a picture of a blue snail with a lavender shell, above it says "All organic" and below it says "Nature's Science Snail Food. The color scheme however was different in "Larry's Gym." It appears as a large bag of snail food that is pink in color on the outside. It has an image of a snail in the middle and the words "All Organic" above the snail and "Nature's Science Snail Food" at the bottom in dark purple with "Snail Food" being in a smaller font size than "Nature's Science."
Role in series
SpongeBob gave Gary this instead of the fungus in "Fungus Among Us" and later was seen during a flashback in "Larry's Gym" where SpongeBob was seen trying to lift it presumedly trying to feed Gary with it. However, when he tried to lift up the large bag, his arms came off.
The snail on the bag in "Fungus Among Us" has a similar appearance to Gary, but the swirl like stripe is purple, the shell is lavender, and has no dots.
