Funny animal, what is it?

Funny animal...

We’ve seen this animal in Artis yesterday.. It seems like a kangaroo but it isn’t really a kangaroo. The body of a kangaroo is much larger and it has much smaller fore legs. This one has 4 equal legs. I know I saw the name on the placard at the fence. It was something like myra....(?) or something like that.... I don’t remember…... This photograph is maybe something clearer as yesterday’s photograph..... Does somebody perhaps know what kind of animal it is?
