I just heard two different kinds of Rumbles

So truffle was sitting there, and I offered him a grape. He very happily took it laid it down did a little popcorn and gave a medium picture semi-rapid Rumble indicating his appreciation

Cinnamon that idiot didn't want to come over. So I tossed him the great. He kept staring at me and walked past the grave and got too close to truffle.

Much lower pitched sparsed out rumble

You don't have to be a guinea pig to understand thanks and sod off in their language
