Boggling Walternate

I was not expecting to get this darling video.  I had just wanted to get Walternate's darling face on camera, but then he started boggling.

He starts with a brux.  Bruxing is when a rat grinds his teeth together.  It's like purring.  They are perfectly content and happy when bruxing.

The muscle that a rat contracts to grind his teeth actually runs behind his eyeball, so if a rat intensely bruxes, their eyeballs will bulge in and out.  And, that's a boggle.

Here, Walternate bruxes and then revs up to a full -blown boggle.  You can actually hear the brux in the video.
