The Travels of Bubba and His Trusty Pink Suitcase

So, G has this pink Dora backpack/suitcase thing that S has adopted for his very own. He loves that thing. He pulls it all over the house and the yard. It's been really helpful actually. I am able to tell where he is at all times just by listening for the wheels of the suitcase rolling along. It's like a dog collar that jingles, only it's a pink suitcase, not a jingly dog collar, and he's a child, not a dog...
