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.
