SpongeBob SquarePants is a Russian hack of the game Cool Spot for Sega Genesis.
Overview
The hack uses the European version of Cool Spot as a basis, as said version removed the 7up references from the game, SpongeBob doesn't have them either. The hack is also in Russian and starts at Wading Around (the fourth stage in the original game) instead of Shell Shock. Strangely, level 2 is the same as level 1.
According to a translation of the beginning screen, the story is that SpongeBob receives a mysterious letter that mentions about SpongeBob's brother needing help.
