It could likely pick you up given the chance. Strange's eyes widen because in that moment, he knows exactly what he must do.

"See if they can pick me up," he says, without any regard for personal safety, grinning slightly as he nudges one of the tentacles. Strange isn't too worried. Once the thing's picked him up and is holding him in the air, all he has to do is turn back into smoke and float back down to the ground! This is a perfectly sound plan!

And if he doesn't turn to smoke in time...well, he saw Tamaki around here somewhere. The kid had healing magic, didn't he?
