I read a thread about massive destruction weapons. It was interesting. I wanted to suggest some also.

Balloon Bomb - an air-based (like air attack and mine strike) attack that is affected by wind, and does from 50-150 damage

Super Watermelon Bomb - A watermelon bomb, but can be detonated.

Flower Pot - Like a dynamite, but when explodes, 2 pieces fly out. When those break, 2 smaller pieces fall out of each pieces, making 4. It ends there. (the first pieces do about 75 damage each, and the smaller ones do 50.)

Drill missile strike - based off mole squadron

Bouncy Bomb - Comes from sky. Set fire area. Drops about 3 bouncy balls. When it hits ground, it bounces again, but gets smaller. All of them do this until they disappear completely.

Wedding Cake - Like the cake. Much bigger in size. Cannot be detonated. sets off when it touches the first hog, or after 20 seconds. When explode, little bits fly off and blow up too.

Nuclear Fission - Starts sudden death.

Lob-o-matic - like a mortar (but no little balls come out when explode), but as it sails through the air, it leaves a trail of small white balls. When the mortar comes into contact with an object and explodes, the white balls fall one at a time. These explode once they touch the ground.

I hope you consider these.
