My transformation is a bit different than yours. Don't ask how drunk I was with Geralt when we made conclusions about how this works, but I become enough bats to equal my body weight, so I'm more of a swarm. I'll have one bat be the primary bat you'll be focused on, and the rest will hang up on the ceiling. Try and do what I do, and I'll try to respond to messages.

[There's no waiting for approval. Only an explosion of bats.

Lots of them, squeaking in a chaotic swarm and moving up, up, up into the rafters in murmurations like starlings, a single bat staying behind and landing next to Batstarion.

That bat looks his paler friend and gives a little wiggle of his own ears to confirm that they're ready to start.]
