|~ Dennis about the Bat Cronies.|
When Bela arrives with Vlad's invitation letter from Mavis, he shouts in outrage about the party and his suspicions of humans being there, causing the bat minions in the cave begin to follow Bela's lead and shout and fly around in anger, but Vlad quickly calms them down.
Later, after Dennis transforms into a vampire and attacks Bela, Bela calls out for the Bat Cronies. All the way inside the cave, the bats hear Bela's call, and all fly out towards the hotel to aid him.
After Dennis defeats Bela, he uses his new-found vampire abilities to sense the army of bats approaching. Dennis transforms into a bat and flies off to face them, with the rest of the group following close behind. The army tries their best to fight off the Hotel's guests, but find themselves no match for them. The bats cry out in pain and all presumably retreat back to Vlad's cave.
