Trivia
A.R.I.A.'s bloon form.
S.P.I.C.A.'s bloon form.
- A.R.I.A. and S.P.I.C.A. are actually not blimps. In fact, they're noble bloon princesses with no combat capabilities whatsoever, so they'll just flee from the battlefield once their blimps are destroyed. Their blimps are actually a gift from their father, Genesis Bloon. The bloon forms are only for graphical and story purposes though.
- Despite being colored like a M.O.A.B, they are actually a B.F.B edits.
- The BGM of the boss fight of S.P.I.C.A and A.R.I.A is an instrumental version of... SPiCa then ARiA (as ARiA is the spiritual sequel of SPiCa)
