An adult Gugugaga penguin. They are fundamentally cheeky, and some carry babies or eggs in their bellies. They wear collars around their necks. They eat leftovers. They only speak in sounds like "Gugugaga," "Guguyaya," "Gugaa," "Gugya," or "Gya." When hit or scolded, they immediately burst into tears and will offer up their own kind or even babies to try and survive. There are 500 of them in the facility.

A baby Gugugaga penguin. They hatch from Gugugaga eggs. They wear light blue bibs, and unlike adults, their fur is gray; as they grow, it turns black like the adults and the bib becomes a collar. Their personalities resemble their parents. When hit or scolded, they cry immediately and try to save themselves by sacrificing friends or kin. They only speak in sounds like "Gugugaga," "Guguyaya," "Gugaa," "Gugya," or "Gya." There are 250 of them in the facility.
