Yogi Bear

Yogi Bear is an action game that was developed by Dalali Software for Piranha and released on the Sinclair ZX Spectrum, Amstrad CPC, and Commodore 64 in 1987; it is based on the Hanna-Barbera television series of the same name which ran from 1960 to 1962 (but Yogi and Boo-Boo reappeared on The Flintstones in 1963 to steal Fred and Wilma's pic-a-nic basket when they went caravanning).
