The Bathroom is the second stage in the Stories of Legend sub-chapter 22, Prince of Darkness.
Trolly Blogger appears as a peon.
Master A. appears as support.
R. Ost appears as a constant threat.
Cat Line up: Your 4 meatshields, King Dragon, Crazed Dragon. Crazed Sexy Legs(unnecessary for one star but use him to make things easier) , Bahamut, Ururun and a unit to quickly dispose the Master A.
Kill the Trolly Bloggers with a crazed cat and let it die.When the R. Ost is close to your base, spam your meatshields and your Crazed Sexy legs and your dragons and try to keep Ururun and Bahamut Safe. When the Master A Appears when you damage the base, try to kill him as quickly as possible to prevent him from being an irritating support for the R. Osts. When you reach the base after killing Master A. keep on spamming incase another one comes back. If you win, you will have defeated one of the most annoying levels at the time. Uber abuse can make this level quite a cake walk
Strategy 2 by HushT (A. Bahamut w/ Unit Defense)
Line up : Eye of the Storm combo, 3-4 meatshields. I used Crazed Cat (20), Jiangshi Cat (30+2), and Ramen Cat (40+2). You may also want to bring Crazed Sexy Legs (Not necessary) and A. Bahamut.
All you need to do for this strat is to use one of your meatsheilds to kill the Trolly Bloggers, and then spam meatshields to stop the R. Ost. Then spawn A. Bahamut to finish the R. Ost. He should then destroy the base before another R. Ost comes out. (If he doesn't just cat cannon the 2nd R. Ost back so Bahamut can get to the base)
Strategy 3 (ft Tesalan Pasalan.)
Lineup: 4-5 meatshields (I used crazed cat, crazed tank, eraser, macho and Jiangshi.) Paris and any other mid ranged attacker (Macho leg is a good no-gacha suggestion or crazed sexy legs), tanky/ranged unit or a combination of both (I used Majestic Zeus.) And Tesalan Pasalan.
You can fill the last slot with any other unit you think might be helpful for this stage (most notably Bahamut).
Kill trolly bloggers with macho leg cat and wait for R. Ost to come out. He will kill the macho leg cat.
Next send out Tesalan Pasalan. When first R. Ost is dead send out all your damaging units and make sure not to come to the base too soon!
From now on this stage should be a breeze if you make sure tesalan doesn't hit any trolly bloggers.
