Olaf, the garden gnome, wants to impress Siggy with some flowers, so he needs to use his boomerang to stop the hungry bugs that come hidden inside the bubbles.
If the boomerang is not enough to defeat them and the plague became unstoppable, he will need to call his Buddies.
Every enemy has an opponent. Do the right choice and do not waste your defense system.
If at least one flower blooms, you win!
