When you find yourself trying to remember a show (or any works) that's on the tip of your tongue but just out of reach, come here - the collective brain of the TVTropes community can probably help. Post all the details you can remember (examples help). If you're looking for a trope, head over to Trope Finder. Have general questions about tropes? Visit Ask The Tropers!
Was it 3D animation or 2D animation? (or live-action?) Also, around what year do you think it would have been made?
Sorry, I just realised it was under anime (derp!) When did you see it?
between 2006 - 20010 ><
I don't remember an episode where the protagonists fought over doughnuts, but Taro the Space Alien had a kid with a blue alien with big ears:

All i can remember from the show are endless fights over doughnuts between a boy and his blue alien/creature pet/friend. The alien looked like a pokemon that walked and talked and had big ears. It was fat and small and was colored with light blue and white beige.
There was a portal that helped you move between the humans and the "aliens" worlds.
I remember that at the end we found out that the blue alien was a legendary creature and that his brother was killed.
Help me find it, please! Thanks!:)
