I've only ever saw a few episodes of this show when I was younger. I think it was a british show perhaps about a boy who is sent to live with his grandparents on a farm in the middle of nowhere. While on this farm he goes off and finds this what I remember being a small chubby green slimy swamp monster/alien that befriends him(I think), anything more than that I can't remember. I live here in Canada and I think I caught it on TVO during the day.
