- At the start of the battle, 1 Mooth and 10 Squire Rels spawn, delay 1~6 seconds.
- After 40 seconds, the boss, J.K Bun Bun, spawns with unlimited Sir Rels, delay 6~18 seconds.
- After 60 seconds, an Othom spawns.
Lineup: Rich Cat Sr., Schoolbus Nyandam (36), Awakened Bahamut Cat (40), Awakened Ururun (36), Maglev Cat (40), Manic Mohawk Cat, Manic Eraser Cat, Eraser Cat (20+70), Metal Cat (20), Octopus Cat (30+2).
To start, immediately spawn an Octopus Cat to stall the Mooth. Send out a second Octopus when you can, but keep saving money. Then rush to spawn Ururun, stall with one more Octopus and a Metal Cat. Ururun will almost land an attack and get knockedback, hit the Mooth with Maglev to max your money, then you can stack your 3 legends. Use Metal Cat whenever possible and use Maglev to finish off the Sir Rels after they take a hit from Ururun.
Most of the cat levels aren't that important, but the Erasers need to survive one hit from the Othom. The legends being high leveled just ends the stage faster so that you are less likely to make a mistake.

As soon Squirrel hits the base, send Fishman Cat and start spamming everyone else except combo cats.
