How can you pin the Penguin Suit Guy down? I like penguins and so I was really amazed to find the Penguin Suit Guy in Collectible Minifigures Series 16:



But despite coming with the 88646 tile he won't stick to it because of the skates:



There's no place to receive studs or anything else on the back of the legs.  So how can I keep the Penguin Suit Guy from bouncing around in his display case for ever more?  Is there a way to easily attach to the skates and not break too many LEGO best practices?
For any CMF's with skates, I put the figure on the stand with no footwear, and attach the footwear to the holes behind their legs.  That way their accessories are there, and stuck to the figure, but the figure is on its stand!
