Fukusuke (フクスケどん, Fukusuke-don) is an owl who watches over Tomy-T and Eggy-P's orchard. He seems to be fond of Marron, and never dares not to listen to her pleas, even when he's sleeping. Hamtaro even imitates her in Smell Strongly, Marron! to encourage Fukusuke from falling asleep!
The name Fukusuke in Japanese means "large-headed dwarf statue", or "bringer of good luck".
His Italian name is Gugufo.
