Clifford Cleans His Room Clifford the Big Red Dog : Season 1 Episode 67

Clifford's good friends come over to help him clean out his doghouse, determined to get rid of all the old "junk" he no longer uses. But before long Clifford realizes that each item holds a special memory and can't be parted with. Mac thinks this is nonsense, until he is reminded of a memory in which he was included. He then understands, along with Clifford, that one dog's "junk" can be another dog's treasure.
