- 1 THE SLOTH spawns.
Start by saving money, send Wall Cat, Sexy Legs Cat, and Paris Cat to keep the Teacher A.s and Master A.s at bay. When they are defeated, spawn Ururun or an Uber Rare with decent range and get ready for the boss wave.
After you hit the base, the main threats are the Shadow Boxer Ks as their high DPS can shred through your frontline. Their main weakness is their high knockback count so a constant stream of Paris Cats can continuously knock them back until they eventually die. The rest is much easier, even THE SLOTH, since it's slow movement speed and attack rate allows it to be easily stalled.
- I L U is slang for "I love you".
