Big's Fishing Derby (ビッグの 釣りダービー) is a hack of Sonic the Hedgehog for the Sega Mega Drive/Genesis by flamewing that allows the player to play as Big the Cat on various fishing levels. Platforming is gone and the game takes place by a series of bodies of water where the player must catch Froggy while avoiding hooking underwater badniks. Eggman also competes with Big in the race to catch Froggy.
