How To Do It
First find a target yard, next fling in the monsters of your choice, Fomor, then Krallen and catapult the ten million putty rage on them after this you can just watch how the yard gets destroyed.
Used For The Monster Bunker
You can also use this for the Monster Bunker with the exception of no putty rage. You can test this method by using the Wild Monster Baiter but however, you must have a Fomor to make this test. This required any level of Fomor (Recommended if Level 4+) because the champion, Fomor, only have the buff ability (excluding Krallen on the Monster Bunker tip).
