Even easier method for the last level from left to right is 2 rows fully upgraded spikes, 2 rows fully upgraded pits, 2 rows fully upgraded spikes, 2 rows fully upgraded archers. All I had to do was cannon every now and then and lightning the dragons. Was long, but very easy
Deck out the drones, buy all 7 specials, send out as many drones at the start as you can and then wait about 5 seconds and use specials 2-6. Gets the drones almost all the way to the end.
I won the last 5 levels that way.
sorry
no RSPCA, I am not mistreating my dolphin.
I am teaching it to fly. It is his fault that he bellyflopped into the water from mars and is now dead.
@doom
battle arena is really your best option for money
use the garden and button too if you have your boosts relatively high
and to get points, you onlyt need to win a race
