Mail Mix-Up

Season 1 Episode 14 | 12m 31s | CC

Duck offers to help Kangaroo deliver letters to his WordFriends, but he forgets Kangaroo's instructions and delivers the wrong letters to everyone. Duck discovers that there sure are a lot of words that end with the sound "ail"-such as NAIL, PAIL and SAIL-and that they sure can't be used interchangeably!
