nevermind, just did it...
1- use only turtles: keep them in the aura so they heal while they defend and enemies became a big number
2- use magic now and then to kill some enemy (just don't pus them away
3- when you have enough enemies use all monkeys\pensuins you can all at once and with the kills you can win the level...
p.s. if you don't spawn 2 tutrles in the first 30 seconds and another turtle regularly you just won't win the level...
