When Taako sees the tumble that Foster takes, sees him freeze to one of those icy blades, he rolls his eyes so severely that his entire body leans into it, and then casts something else entirely.

Beside him, in the only clear space he can find, a creature appears: a quasi-real horse-like creature, as a matter of fact, in pure white, two rainbow horns emerging from its head. The binicorn turns to Taako and juts its chin out by way of greeting, and then it speaks:

"Let's go, my main man."

Taako is on Garyl's back before he can even think about it, attempting to ride him inbetween the blades and the rest of the crowd, charging towards Foster to try and aid him a bit more directly.
