While living on Earth, Froggy found and was forced to swallow a puddle of water that was Chaos when he and Big found a Chaos Emerald, causing Froggy to grow a tail and act strangely. Immediately after swallowing Chaos, Froggy indigested Big's Chaos Emerald and ran off. Froggy was eventually found by Big and Chris, but was immediately after abducted by E-102 Gamma and brought to the Egg Carrier. There, Froggy was placed in captivity, but was freed by Big and Chris. After escaping, however, Froggy was caught by Dr. Eggman, who made him regurgitate the Chaos Emerald. Froggy was then absorbed by Chaos where it regain the part of it Froggy had swallowed, returning Froggy to normal. Shortly after, Froggy was freed from Chaos when Sonic the Hedgehog and Knuckles the Echidna defeated Chaos and he and Big returned to their home.
