Students at Austin's Allison Elementary get a special treat Tuesday -- courtesy of their principal.

Guadalupe Velasquez set up office on the school's roof -- in a chicken suit.

He is doing this as a reward to the community for doubling membership to the PTA.

Last year there were 60 members -- this year he wanted to reach 160.

They reached their goal.

Velasquez even started dancing with some of the students who came to visit.
