If initially spoken to while wearing the Jack lantern mask from the 2006 Hallowe'en event, he will start off by saying "What-ho! Now there's a good looking chap!". When speaking to Pumpkin Pete wearing the mask during the event, he may add small phrases like "Still looking good, I see." Female characters that speak to Pumpkin Pete for the first time whilst wearing the Jack lantern mask will get "What-ho! Greetings, fair lady."
His Jack lantern mask is different compared to the 2006 Hallowe'en event reward; it is bigger and has lighting effects.
He may be a reference to 'Peter Peter Pumpkin Eater', a nursery rhyme.
