Play as Tinkerbat
To begin, this game must be played on a Game Boy Advance instead of a Game Boy Color. When you start up the game, the title screen will say "GBA Enhanced!" in the bottom-left corner if the game recognizes the system properly. This changes the palette for the game slightly, and also an NPC in Bandit Town will now offer to tell you a secret for 500 gems. If you enter the "Advanced Genies!" building and pay up, you'll unlock a new dance, which can be performed by pressing Down, Up, Up. The dance allows you to play as a Tinkerbat. In addition to a sabre attack with a decent range, the Tinkerbat can run, jump, and climb walls like the monkey; charge foward like the elephant (by holding down and pressing B); and climb walls like the spider.
