Like most of the gang, Jazz has a lazy streak, but if you find Jazz lazing about, say upside down on the couch when he’s really not supposed to be in the house at all, he will tell you he was practising his special skill and just happened to doze off.
It’s hard to argue with that because Jazz’s special skill is to do with upside-down-ness … and running water. It’s a useful skill particularly to the unicorn (but of course that’s part of the secret that we’re not allowed to talk about yet) so Jazz is usually allowed to lounge about as long as he’s upside down.
