In-Flight Slumber
帰りの飛行機は全員熟睡
In-Flight Slumber is a Battle Cats stage in Season 3: Field Trip. It costs 250 energy and sends 13 enemy spawn lines — led by Nimoy Bore as the boss — against a 450,000 HP enemy base, and clearing it rewards 310,200 XP. Its enemies carry the Alien trait, so cats that target it do the most work here.
