The farm's co-owner, Sandy Bonem, posted a video online of the horse opening numerous locks. It catches how Mariska lets herself out, then unlocking stalls for other horses — just not her mother's.
As of Monday, the YouTube video had more than 760,000 views.
Bonem tells the Saginaw News that Mariska, "doesn't like to be locked in."
Bonem says Mariska played with things in her mouth when she was young, and "she just kind of progressed."
