Mr.-ious Evolution (Insane) is the second stage in Mr. Awakens!.
After the base is hit, an Angelic Gory, a Heavenly Hippoe, a few Wall Doges, and, most importantly, 3 Hyper Mr. appear. Most of these enemies are spawned at a mild pace, and Hyper Mr. appears in groups of 3 every 2 minutes or so.
Strategy 1 (ft. Cyberpunk Cat)
Lineup: 2-3 cheap meatshields, Jiangshi Cat, Ramen Cat(34+3), Cameraman Cat/Cyborg Cat (or both), Cyberpunk Cat, Awakened/Crazed Bahamut(30), Ururun Cat, Holy Valkyrie Cat(can be replaced by a high damage Uber, Dark Catman worked really well).
Items: None Required
At the start spawn some Ramen Cats and level up your Cat Wallet to about lvl 4. When you get a bit over the middle start sending out all your cats, except Valkyrie (and Bahamut, if he's Awakened), Don't spam too much, else you'll hit the cat limit!
When you hit the base start spawning all your cats, and you should be able win!
