Ninita the pygmy marmoset knows how to appreciate the simple things in life. Like her toothbrush, for instance, and ... actually, that's about it -- she really loves her toothbrush.
Ninita was born deaf and rescued by the Rare Species Conservatory Foundation in 2012 after her parents abandoned her as a baby. She's been hand-reared ever since, and has developed a love for playing and toothbrushes which persists to this day:
According to the San Diego Zoo, pygmy marmosets are the world's smallest monkey. When fully grown, they weigh about as much as a stick of butter.
