You are doing a fine job with Moo Moo. Is he going to be wearing anthing cool, like maybe some bib overalls, straw hat, anything? I think he would look fine in a bright plaid flannel shirt too.
another quick, easy idea to make him one is to castrate him. Wouldn't that make him a wether goat? That would be a lot quicker and easier than teaching him to be a meteorologist?
I think you should put little treats in the weather chart, teach him to look around for treats, or to go get them when you point with a stick. Now THAT would make the killer weather goat!!!
