Pumpkin design -- with poor crated puppy as onlooker (he couldn't stop barking outside).
Carving solo. (I decided, after cutting the upper lid off the pumpkin myself, to let 5-year-old Will do everything else himself -- gutting, face design, and yes, carving, but with one of those relatively harmless pumpkin kit carvers.) We wound up with a giant-eyed, teeny-mouthed pumpkin, but Will loved being in charge and I was quite satisfied with my role as pumpkin seed roaster.
When mom won't let you carve the pumpkin, at least you can play in the guts.
