Zerby Derby

Chase is getting a new decal.  But Mika tells him he can’t fly for a full hour while the glue dries.  Chase realized NOT flying is harder than he thought it would be. - Strut has created a new, long bridge.  But it sags quite a bit in the middle.  Zack and Strut know they can solve this problem.  But with what? - Zack wants to build an obstacle course.  He can see it perfectly in his head.  Unfortunately, he isn’t doing a great job explaining what he wants to Rex and Strut.
