One of the classrooms at the high school has been vandalised. Lena's band, the Screeching Vampires, has been accused of the attack as they were the only people known to have been on the premises at the time as they were rehearsing for their forthcoming gig. Randy has also been blamed as he was watching the rehearsals. The pigeons summon Pigeon Boy to prove that the Screeching Vampires are innocent by finding out who the real culprits are and exposing them.
