Yogi's Big Clean Up is a platform game, that had been developed by PAL Developments, for Hi-Tec Software, and released on the Commodore Amiga in 1992; it is the fourth title in the Yogi Bear series, and the player must help Yogi collect or fix items (which are represented by eight "I"s at the top of the screen). His energy is represented by a knife (to the left of the eight "I"s), and he gains it by collecting his show's trademark picnic baskets (as long as that bothersome Ranger Ned Smith is not watching), but if he should ever run out of energy, one of the three prongs on the fork (which represent his lives) will disappear - and if the last prong should disappear, the game will be over. However, Yogi will gain the prongs back at 20000 points and every 30000 points thereafter (if he does not still have all three).
