Froggy

Froggy(カエルくん Kaeru-kun?) is the amphibian pet and best friend of Big the Cat. He is the main objective of Big's storyline in his debut in Sonic Adventure. Froggy also has a critical role in the game's plot due to it swallowing a Chaos Emerald and portion of Chaos' tail. This spurred Dr.Eggman to dispatch his army of E-100 series to capture the amphibian; resulting it also becoming E-102 Gamma's objective in his storyline. Chaos' absorption of Froggy and re-acquisition of its tail caused the beast to take its Chaos 6 form.

Froggy's relevance is also prominent in Sonic Heroes of he and Chocola the Chao are kidnapped by Metal Sonic. Metal Sonic's purpose of acquiring Froggy is to extract information about Chaos' shape-shifting ability within the frog after the events of Sonic Adventure. Big is naturally compelled to save his friend with the help of Cream the Rabbit and Amy Rose. Since he is usually accompanied by his owner, Froggy's role has also been reduced to cameos in the following Sonic games. In Sonic Chronicles: The Dark Brotherhood, Froggy assists Big in combat with the moves of "Froggy Rain" and "Froggy Poison", which are POW Moves in the game. Froggy is also Big's All-Star Move in Sonic & All-Star Racing. He appears to be about two to three times Big's size and will hop down the race track to plow down anyone in his way.
