Simple puzzle game, where you have to make worms to suck on each other. It's a whole lot like Sega's Puyo Puyo. Virtual Lab is probably the weirdest of all Virtual Boy games. For example they misspelled Nintendo wrong two times, once "Nintenndo" on the box and then "Ninntenndo" on the cartridge. Plus the game gives you a password after every level, but there's no way to put them in! If you can manage to beat Level 100 anyways, that level will replay again and again, no matter how often you beat it. So there's no real ending to this game.
