"I've spent the last five years cultivating luminous pumpkins, flying pumpkins, singing pumpkins and exploding pumpkins...."
-- Dagbert Pips to the Daily Prophet (DP4)
Dagbert Pips was the proprietor of Pumpkins R Us (DP4).
Pips complained to a Daily Prophet reporter that a restriction on Hallowe'en celebrations would hit pumpkin-growers particularly hard (DP4).
Dagbert is Old German for "bright day, shining day" and is a variation of Dagobert.
