Zerby Derby

Zack finds Lily and Axle covered in mud and each missing a tire.  There’s definitely a story behind what happened, if only Lily and Axle can get it in the right order… - Flynn is a float plane.  He has floats.  But the new Zerby Town Airport has a runway for him to land on, and there are wheels he can use.  But how does he land and put on wheels if he can only land on water with his floats?  Zack and Rex help Flynn figure it out. - Strut has constructed a tower out of sticks.  Zack and Lily agree to help him move it, but if they make a mistake it will fall and break.  Usually Zerbies try the first idea and just try, try again if it doesn’t work.  But this time they have to get it right on the first try.
