Froggy

Froggy is Big the Cat's friend.

History
Froggy has eaten both a part of Chaos and a Chaos Emerald. Abducted by E-102 Gamma, Froggy was taken to the Egg Carrier as Dr. Eggman wanted the Emerald and Chaos piece inside him. Big pursued him, and recovered his friend. However, the Chaos Emerald and the part of Chaos he had swallowed were absorbed into Chaos, allowing it to become Chaos 6, but was eventually rescued by Big with the aid of Sonic. Big and Froggy then took the Tornado 2 back to Mystic Ruins.
