Five Years of Fun!!

Five Years of Fun!!, is a limited time event from the Birthday Present! stage.

Battlegrounds
The battle starts with 5th Anniversary Birthday Cake with 2 Doges and Firework Guys. Then the base will spawn Doges and Fireworks Guys in a slow pace.

Strategy
The Birthday Cake #6 seems to be a tough opponent (it's considered metal). Spamming quick units such as Cow Cat, Crazed Cow Cat can get the stage beaten easily. Bring Hurricat or other critical hitters to finish the stage faster.
