Giant Baby

The Giant Baby is a boss faced in the video-game "Zombies Ate My Neighbors" - appearing (unsurprisingly) as a gigantic toddler this boss is most likely a result of the many mad experiments of the game's main antagonist Dr. Tongue, though how and why this particular baby grew so large is left to the player's imagination as the game didn't dwelve far into plot (being a parody/homage of many horror cliches).

As a boss the Giant Baby can be difficult or easy depending on your relative skill and caution, once defeated the Giant Baby shrinks down to normal size and can be rescued just like the other "victims" in the games.
