Mamegoma

Mamegoma (まめゴマ) is a series of seal characters created by the Japanese company San-X.

Mamegoma are available in a variety of different colors including, white, blue, pink, yellow, and black.

The seals are often depicted as being small enough (12 cm, weighing around 200 g) to live in a common goldfish bowl, usually with a few ice cubes to keep the water nice and cool.

They are also shown in advertisements and merchandise in bath tubs and relaxing on a wheel in a hamster cage among other activities.

(クプ～！！まめゴマ！) is based on Mamegoma, revolving around 'Mameta' the Shiro-goma and some other seals going by Soda-kun, Cherry-chan, Candy-chan, Samantha-chan, Daigorou-kun, and Lemon-chan.
