Littering Coast is the fifth stage in Sub-chapter 26, Sea Polluter.
Battleground
A challenging and banterous stage. At the start, an incredibly magnified Wall Doge will spawn. Groups of three Assassin Bears will spawn in long intervals throughout the battle. DO NOT fire the Cat Cannon unless you're killing the Bears.
Strategies
Get treasures that max your Cat Cannon damage and charge time. This will help you kill the Bears. Use of Maxed Out Cat Combo is almost required.
