Fluff McGuffin

Fluff McGuffin is a toy that D.W. wanted for her fifth birthday in "D.W. and the Beastly Birthday". D.W. calls it "Fluff McGuffin the magic puffin". After hinting about it several times to her family, it is Arthur who remembered that she wanted it so badly, and he got it for her from David's Toys.
