I cannot for the love of me remember this movie. I used to love it as a kid. It was a young boy who finds a kid alien who got lost from his parents. He's kind of pinkish in color, really cute chubby cheeks. There's a birthday party scene in Mcdonalds,um and the human boy ends up helping the entire alien family all get off the planet. This was not an animated film, or anything like that. PLEASE help! This would be greatly appreciated!

Possibly Mac and Me (1988) (http://www.imdb.com/title/tt0095560/) ?

Yes, is that one. I remember well that Mcdonals scene.

Thanks you guys! That was it! I found it on YouTube, it's in 9 parts. Haha I feel like strolling down nostalgia lane. :D
