In the game, the player plays a small alligator known as 'Charly' who whips his tail forward to attack.

The story of the game centers on the conflict arising from a dragon warlord known as 'Basso Gila' who teleported his castle and army to the peaceful animal kingdom of 'Moberry' in order to destroy it and establish his ultimate rule.

The council of elders of Moberry put Charly, the highland alligator, on the task to send the invaders packing in order to ensure their well-deserved freedom.

There are five areas in Tail 'Gator; the first three are divided into four sections revolving around recurring themes: Air, land, cave, and underwater.

When Charly kills an enemy (normally two tail swings), it will eventually respawn at its starting point.
