A Chipmunk Reunion is a 1985 animated special produced by Bagdasarian Productions, in association with Ruby-Spears Enterprises, and is spun off of NBC's popular animated series, Alvin & the Chipmunks, starring the Chipmunks and the Chipettes.

Plot

Alvin, Simon and Theodore argue about when exactly they were born. But not even their adoptive father, Dave Seville, knows the exact date (he celebrates their birthday on the day he found them), so Alvin decides that the only way to find out would be to look for their long lost mother. When Dave comes downstairs the next morning and sees the Chipettes in the house (the boys asked them to look after Dave), he realizes that the boys went to find their mother, and fears that they could get hurt by wild animals in the forest. So, he sets out to find them, while the girls join him on his search.
