Goolet is a bit of a swamp potato. He never leaves his goopy swamp and has little ambition except to eat goop and goop-covered weeds and snails. As you might guess, Gooplet is a mamma's boy and lives in his mamma's swamp even though there's an inexpensive swamp right next door he could probably afford to buy with his allowance. - Bret Petersen, creator of the Gooplet
The Gooplet is a Maxis made creature, present in the final game. They are small reptiles with almost no legs and a very large head with two large ears. They are sapient creatures and evolved until Space stage.
Gooplet isn't good at combat. His only mean of attacking is a weak bite. When socializing, they are bad singers, but are great at charming.
