BOSS
KAPPY JR.
Water Conservancy is the 3rd stage of Bottom of the Swamp. Previous stage: Guided by Currents.
STRATEGY
Kappy Jr. plus Relic support, and every unit you place badly becomes another Surge Attack aimed at your own line.
- Use ranged meatshields such as Mer-Cat so his Surges miss more often.
- If you bring Cameraman Cat, bring Research Up Cat Combos with it.
- Weightlifter Cat and Surfer Cat add ranged damage that does not feed the Surges.
- Fast, cost-efficient units like Slime Cat or a talented Hip Hop Cat keep the pressure up between waves.
