Some ambiguity as to whether it is in fact a xylophone/cat or a xylophone/platypus. In either case, a living specimen has yet to be found and is currently theorized to occur only in high temperature climates.
Guy: I heard someone talking about a xylopuss the other day...wtf?

Girl: I think it's a fun name for keyboard cat, but with a xylophone...

Guy: How do you know it isn't a platypus rocking out?
