|Fairy Tale:||Gulliver's Travels|
|Appearances:||Once Upon a Crime|
Swift describes them as, filthy and with unpleasant habits, resembling human beings far too closely for the liking of protagonist Gulliver, who finds the calm and rational society of intelligent horses, far preferable. The Yahoos are primitive creatures obsessed with "pretty stones" they find by digging in mud, thus representing the distasteful materialism.
In The Sisters Grimm, Yahoos are brought over on the Neuer Anfang because Gulliver believes they can be civilized, a huge mistake on his part. They colonize the New York subway system near Faerie and are a huge nuisance to the the six dwarves as they regularly attack subway cars. When they attack one with the Grimms on it, Daphne helps to fight them off.
