50 Degrees Hotter is the fourth stage in Mouseyland.
Cat Lineup: Mohawk Cat, Manic Mohawk Cat, Eraser Cat, Crazed Wall Cat, Crazed Whale Cat, Crazed UFO Cat, Maglev Cat (Optional, but really helpful), Jamiera Cat, Crazed Mythical Titan Cat, Awakened Bahamut Cat
When Zamelle spawns, start spawning Erasers. After some time, start spawning Crazed Mythical Titan, Jamiera, and a few Crazed Whales. When Zamelle's dead, let Maglev do the damage to the base. There are 3 sets of Brollows with 8 Brollows each. Each set appears on every 4% damage to the enemy base, which means, every 16.000 damage will trigger one wave of Brollows. Therefore, a wave of Brollow appears when the enemy's base health reaches 384.000, 368.000, and the last one at 352.000. This also means that if you hit too hard (eg: having Bahamut to instantly deal a massive damage on the base), you will trigger all 24 Brollows, which would be trouble, so try triggering the Brollow's waves one by one.
When the Brollows spawn ,start meatshielding, spawning Crazed UFO, etc. Once the Brollows are dead, return to your normal slow spawning. Repeat this process 2 more times, then at the end, spawn Awakened Bahamut to quickly finish the Base off.
Another strategy that can be used in this level is by utilizing Hyper Mr., which have a Zombie Killer ability. Depending on the star of the chapter, one can calculate the damage done on the Zamelle and count on how many health does the Zamelle have left by carefully doing damage to it. Once its health reaches low enough, one can spawn Hyper Mr. to do the finishing blow on Zamelle, thus completely removing Zamelle out of the threat. This can also be done with the ubers in the Iron Legion set.
Another counter for the Brollows is Commando/Cameraman because of her strong ability against Floating Enemies. The only problem with this strategy is that she will get destroyed by Zamelle in higher stars, so this strategy only works in low stars.
- The title of this level appears to be a reference to Fifty Shades Darker, an erotic romance novel by E. L. James.
