Froggy (カエルくん Kaeru-kun?) is a character that appears in the Sonic the Hedgehog series. He is the pet frog and best friend of Big the Cat, though he has a habit of running off on his own, leaving Big to set off each time to find him.


Froggy is a green-skinned non-anthropomorphic frog with a round body and four limbs. His limbs are rather thin, and each one has webbed feet with two toes each. He also has a white underbelly, orange stripes around his body, and red dots on his cheeks. He also has medium-large eyes with pale yellow sclera and wide black pupils.

After drinking Chaos' essence, Froggy gained a tail with a triangular tip. He supposedly lost it after Chaos' essence was returned to him, though it has made several reappearances in subsequent games.




Years ago,[2] Froggy met Big and became his pet and best friend.

Sonic Adventure[]

In Sonic Adventure, its enhanced port Sonic Adventure DX: Director's Cut, and the 2010 remaster, Froggy swallowed both a part of Chaos and a Chaos Emerald. Abducted by E-102 Gamma, Froggy was taken to the Egg Carrier as Dr. Robotnik wanted the Emerald and the 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 him 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.

Sonic Heroes[]

In Sonic Heroes, Froggy and Chocola (Cheese's twin) were abducted. Big, Amy and Cream went to look for them under the impression that Sonic had taken them. During the adventure they instead figured out that Dr. Robotnik, now known as "Eggman", had kidnapped Froggy and Chocola, and defeated him. However, it turned out that Metal Sonic had framed Sonic and Eggman and had kidnapped Froggy and the Chao in order to copy the residual data of Chaos. When the treacherous robot was defeated, the frog and Big returned home.

Sonic Colors[]

In the Nintendo DS version of Sonic Colors, Froggy ran off on his own once more and supposedly made his way to the Aquarium Park in Egg Planet Park. Hot on Froggy's trail, Big followed him to the area, where he looked for him. There, Big met Sonic and Tails and got Sonic to look for Froggy, but without results. Sonic, however, suggested that Froggy could already have gone home by then.

In Sonic Runners, Froggy made a few appearances during exclusive Events. During the "Birthday on Windy Hill" event, Froggy came to Sonic's birthday party with Team Rose, where they got kidnapped by Dr. Eggman when he trashed the celebration with his miniature Death Eggs. Thankfully, Sonic showed up in time to free Froggy and Team Rose (except for Amy who got away), and the group returned to celebrate Sonic's birthday after Sonic got rid of Eggman.

During the "Tropical Coast Event", Froggy accompanied Team Rose to a beach resort. Amidst their relaxation, the group met Team Sonic. Once Team Rose learned of Eggman's most recent scheme, Froggy came along with Team Rose when they decided to help Team Sonic stop Eggman.

Sonic Frontiers[]

In Sonic Frontiers, Froggy is mentioned by Big the Cat in the Fishing Spot for liking Purple Coins.[1]


While unable to express himself vocally, Froggy has shown other ways to define himself: one of which is his rather bad habit of running off on his own, leaving his best friend to chase after him. When reunited with Big, the frog appears to be content with returning to his home at the Mystic Ruins.

IDW Publishing[]

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, Froggy acts similar to how he does in the games. He is a simple-minded frog that does whatever he wants at any given time. Though he is not known to exactly listen to anyone, he can be slightly obedient with Big.


Big the Cat[]

Big is Froggy's best friend. He enjoys his company and lives with him in the Mystic Ruins. Sometimes, however, Froggy has been known to run off independently away from Big, which prompts Big to come looking for him. However, he is always glad to be reunited with him and come back to their home.[3]
