How were Glukkons and Vykkers able to clap at the Gabbiar Auction?
While neither species seems to be built for clapping, Glukkons do have small legs they can allegedly clap with (though they appear vestigal). Vykkers actually have two sets of arms to clap with, and are fierce clappers even without their clapping amplifiers— Vykkers are great showoffs and like people to believe they are better at clapping— of all things— than they actually are.
