The Kusa Mochi has an LP of 50, gives 1 gold when killed and is initially spawned in a group of 20 by the box.
The first upgrade cost $50, and each subsequent upgrade cost $10 more.
Increases the LP of all Kusa Mochis by 10 and gold drop when killed by 1.
Increases the number of Kusa Mochis spawned each time by 10.
Gives a 2% chance for killed Kusa Mochis to revive with full LP per upgrade. The same monster can revive more than once, therefore while upgrading this beyond 100% has no more effect, 100% revival chance will mean an eventual game over as the stickmen will not be able to actually bring the monster count down.
A boss version of the Kusa Mochi with much higher LP can be spawned by purchasing it like upgrades. The boss starts at LV 1 which has 100000 LP. Each subsequent boss purchase spawns a boss 1 LV higher (up to LV 50), which has 20% more LP than the previous LV. When the boss is defeated, it gives the same gold drop as the normal-sized Kusa Mochis and the level cap for the Kusa Mochi will increase by 10, up to LV 600. Costs $(4000+1000x) for monster LV x.
This boss has no special abilities.
