Dave has been getting swimming therapy for his dodgy knee. He is so cold afterwards that he has to now wear this lovely hat. It looked stupid when he didn't have any ears. So ears were made. He doesn't look stupid anymore.
EDIT: Dave has a luxating patella.Or a loose knee-cap in layman terms. It can be quite serious if gone untreated, but thankfully Dave just has a level 1 knee. It can go to level 5. So he has some XP to gather! No, hopefully not. He's in rehab, part of which includes swimming. A full rehab post is in the making...with pictures!
