Apollo and Mysterium are half-siblings, sired by Kreacher.
Apollo is 7 months old now.
Mysterium is 4 months old.
Little feisty wily girl has figured out that she can play with big brother … and that mama is nearby if he gets too rough!
It starts with a bit of nibbling on the shoulder …
About halfway through the game, he decided he could rear up, too.
She did a lot of this …
… and a little of this, but she never actually kicked out at him.
A little more teasing …
… some more near-synchronized rearing …
… and the warning from mama Kootenai (you can just see her pinned ears) …
that led to this:
!!
But it was all good in the end …
And they lived happily ever after. 
Amazing photos.Is it just me or Mysterium looks a little bit like Pygmy goat? So cute <3
Ha – she does a little.
Adorable! I love these! They have so much fun out there…
It’s good to have siblings.
Love the “kids” at play.
Loved watching them!
The ones of them rearing at the same time are beyond adorable!
Just a question TJ. I saw this article (http://dsc.discovery.com/news/2008/10/08/horseplay-mothers.html) About mares playing more with their colts then their fillies. It makes sense, but I was wondering, have you ever noticed anything like this?
I haven’t seen this yet, but I have heard about it, about a year ago, I think. I can’t really say either way from my observations – but I’m not specifically watching for it. It’s not often the mamas I see playing with the foals as much as the stallions and/or siblings (both same age and older), though. Mamas seem a bit more long-suffering.
I enjoy following your site. Thanks again for all that you do. I really appreciate the calendar and the time you spent to make it happen. You are one dedicated lady. Hope to see you again sometime out in the basin.
ELO
