Here's my catus terrarium I kept at work years ago. 

It had a miniature birdhouse and a popsicle stick that had lady bugs and a smiley face made out of  thumb tacks.

When I was in Girl Scouts, one of the things we made was the Monkey Ball Necklace.  But as I was browsing the net about it, I see its called the Monkey Fist Knot Necklace.

I still have the 3 original necklaces I had from Girl Scouts, which inside of each of them I can't recall what it was, maybe a marble or bead.  But whichever, Dr. Evil Jr. was still eyeing them up for his play toys.

I found this video,

its a mega example to show how to make one.

If you like sock monkeys, who couldn't forget the movie Cabin Boy from 1994 when David Letterman's character says "Would you like to buy a monkey? "

Here's my favorite sock monkey included in the pictures below I bought a couple years back at a craft show.
