Soarin might be laughing, but I think he's enjoying it.
Spitfire was born for this parody so it was inevitable.
Maybe she and Soarin are advertising those Wonderbolts swimsuits along with the Copperpony sun tan lotion. XD
And yes, that lobster should be purple but this is a cartoon, physics is irrelevant.
Before I leave I just want to say that Spitfire and Soarin's manes are the most difficult for me to draw...
