Puffer Planet (Merciless) is an Advent Stage appearing on the 13th, 14th, 27th, and 28th of every month. When clearing this stage, the player has a chance to unlock Mightycat. Unlike other Advent Stages, it is only unlocked after clearing Chapter 2 of Cats of the Cosmos. This is a No Continues stage.

- 1 Corporal Weyland spawns after 50 seconds.
- 1 Project A spawns after 80 seconds.
- 4 Star Pengs spawn after 100 seconds, delay 13.3~16.7 seconds400~500f.
- 4 Star Pengs spawn after 160 seconds, delay 10~13.3 seconds300~400f.

Due to the massive buffs on the Starred Aliens (particularly the Star Pengs), it is highly recommended if not outright required to have all anti-Starred Alien Treasures before attempting this stage. Missing even one Treasure set will lead to each Star Peng having 672,000 health and 36,000 attack power, making them nigh-unbeatable without certain anti-Alien Uber Rares/Legend Rares. A highly levelled Catellite can survive with a small margin of health against Puffsley's attack.
It is possible to deal with this stage by letting the boss hit the base, then immediatly unleashing some anti-alien nuker to take away as much health as possible. This can conclude the fight very early if one has the right unit and setup. If this approach isn't possible, it is then recommended to bring units who are able to hit Puffsley's Comet few times, but with strong attacks, while leaving any units who may do the opposite out of the fight. Manic Macho Legs, for example, would only cause more harm than good with his waves.
