Brilliant money machine:
Level 2: The Banana Shire;
Turtle, then lots of goblins and healers, then turtle at the end.
I earn about 3000 money that way, even with only 8 monsters.
To "LOL89078", First, there are no walkthrough because each level is different, even in the same number. Second, If you are stuck at level 2, then you have NO chance of clearing the other levels!
