Game appearances

Sonic Adventure/Sonic Adventure DX: Director's Cut

A Sea Otter in *Sonic Adventure DX: Director's Cut*.

The Sea Otter made its debut in Sonic Adventure and Sonic Adventure DX: Director's Cut. In gameplay, Sea Otters can alter the stats, appearance and personality of a Chao. These animals are found inside Badniks. Simply destroy the Badnik to release the Sea Otter inside, and then touch it to pick it up. When released, the Sea Otters have a green sphere around them, which disappears shortly afterwards. They are found in the following Action Stages:

Upon entering a Chao Garden with a Sea Otter, it will leave the playable character and run around the garden. The Sea Otter will sparkle if it has not given them to a Chao in the garden. Should the player give a Sea Otter to a Chao, the Chao will embrace it, attaining its appearance and behavior and raising its stats according to the Sea Otter's. The Sea Otter will then lose its sparkle and disappear shortly after.

Sonic Adventure 2/Sonic Adventure 2: Battle

In Sonic Adventure 2 and Sonic Adventure 2: Battle, the Sea Otters appear again as Animals used for raising Chao. The way the player acquires the Sea Otters, releases them into the Chao Garden, and uses them to alter Chao, is the same as in Sonic Adventure and Sonic Adventure DX: Director's Cut. The Sea Otters similarly disappear after being used and possess a temporary green sphere around them when released from robots. However, they do not sparkle in Chao Gardens like in the previous title.

In gameplay, the Sea Otters are either found inside Badnik enemies or the second Chao Container opened in an Action Stage, or hiding somewhere in the Action Stages, usually inside Cages or Pipes. They are found in the following Action Stages:

	Hero Story	Dark Story	Misc.
Action Stage	Prison Lane Hidden Base	Dry Lagoon Weapons Bed Cosmic Wall Final Chase	Cannon's Core (Knuckles, Eggman)

Sonic Advance series

Sonic Advance

In Sonic Advance, the Sea Otters appear as victims of Dr. Eggman, who used them as organic batteries for his Badniks. The Sea Otters can be found in Neo Green Hill Zone where they pop out of destroyed Badniks.

Sonic Advance 2

In Sonic Advance 2, the Sea Otters appear as victims of Dr. Eggman, who used them as organic batteries for his Badniks. The Sea Otters can be found in Leaf Forest, Ice Paradise, and Egg Utopia where they pop out of destroyed Badniks.

Sonic Pinball Party

In Sonic Pinball Party, the Sea Otters play a role in the game's Story mode. In this game, the Sea Otters were among the Animals that came to Casinopolis, only to get kidnapped by Dr. Eggman and turned into robotic slaves. To save the Sea Otters and his other Animal friends, Sonic entered the Egg Cup Tournament. Once Sonic completes the game's Story mode, a shot of a gray-furred Sea Otter leaving Casinopolis together with Sonic's friends and the other Animals is shown.
