The majestic land dolphin.

No you hobnob. That's a kangaroo.

It's fun

Landaroo.

My dog does that in tall grass as well. What’s up with that?

It's so they can see what's around them. Also used for hunting, trying to find prey among the grass/weeds.

You are sadly mistaken. This is the rare Great Equipedal Kangaroo

That is so cool. You can see him scan the horizon when he jumps up like he's tracking something's movements in the grass. Fascinating.

Didn't expect that:) definetly made me smile
