The Great Pumpkin

I know that a lot of kids around the age of two have a favorite blanky or a stuffed animal they carry with them, I am sure there is a scientific name for this, but what do you call a kid who is attached to a piece of produce.
Last night we went to a churches Halloween fling/ thing. While there the frog, who we will also call Jonas, accepted a little white pumpkin as a default prize at the decorating table. Evidently black scribbles and stickers on a pumpkin don't even cut it in the toddler category. The nice elderly lady said here is your pumpkin as she smirked and sent him on his way.
This is when his pumpkin affection began, he carried it with him at all times through the day, at bath time, potty time, even tried a few bites of it. We were not aware of his real love for it until bedtime when a stuffed animal was traded for his new best friend , the pumpkin.
Now how do we let him know about what happens to produce after awhile?
