Tough nut to crack!

This squirrel was trying to crack a nut, putting every bit of energy and strength he had into the effort. He made some hilarious faces as he munched and crunched, but to no avail. Eventually the nut fell out of his paws, and he gave up.

I just backblipped for two days: here and here.

BTW I now have posted 400 blips...a day later than I should have because I have been sick this week. It's hard to believe how fast #400 came around.
