Jingle Hell is the second stage in Christmas in Space.
Battleground
One Shy Boy will rush to the Cat Base after a few seconds.
As soon as the enemy base takes damage, Satan Claus, Dark Emperor Santa, Shy Boy and I.M. Phace will spawn with a boss shockwave. Shy Boy continues to spawn in ~20-second intervals.
Strategy
Jingle Hell is not harder than the previous stage, That's Not Santa.... You will only need some anti-Aliens. Units with long range and high damage (e.g. Bahamut Cat are recommended, and anti-Reds could help as well. Units with high health could be useful but they aren't mandatory. If you want, bring along some anti-Floating units for the I.M. Phace and the Shy Boys.
Cyberpunk Cat is a massive help because he can slow the progress of the enemies, especially the Shy Boys.
