Altairian frog

An Altairian frog is a type of amphibian native to the Altair system. They are common pets among children in the Federation.

Their slick skin is rather unique in color, having red and blue spots, along with orange stripes. They have a tendency to climb humanoids legs, mistaking them for tree branches.

In 2364, Oliver T. Hutchins, Jr., a child aboard the Enterprise lost his pet Altairian frog when it escaped into the ship's ventilation system during a "show-and-tell" presentation in Mrs. Kramer's class at 0900 hours. Ship's Crewmaster Lauri T. Masterson sent out a memo to all department heads to be on the lookout for him. (TNG technical manual: TNG: Officer's Manual)
