Invisi-ghoul 2

Invisi-ghoul 2 is a second invisible-zombies minigame that takes place in the Sandbox. It is the bonus level for Sandbox, but the middle lanes are already turned into the pool (so you don't have to manually do it). This mini-game has 3 flags, new plants, and new zombies from the original Invisi-ghoul.

Strategy
Just do whatever you would do for Invisi-ghoul. But look out for new sounds, such as beeping noises (hologram zombie) and for a "Sproing" noise (Pole Vaulting Zombie). If a Gargantuar is about to smash a plant it will roar (it only appears in the last flag and the beginning of the second, only once per flag).
