"Yes! I can lead them there!" He looked at them, fourteen people. "I don't think I can make them all invisible..."

He could try, but he's not sure he's got enough energy. "But if anyone needs help being sneaky I can do it for them, to make it easier!"

And then those who were already good at sneaking could do it themselves! That would be better because he's never tried to make more than two people invisible at the same time before!

"I know where it is though!" He could get them there.
