Upton's Unusual Underwear

Upton Rabbit wears some very unusual underwear. Each one is handmade from the laughing calf to the sneezing bees. They are so funny and unusual I think he should wear them outside. Upton's name makes the short "u" sound. Can you think of other words that begin like Upton's name? Upton has a special song and he loves to play letter sound games. Do you remember how many there were of each character on his underwear?
