answer: the duck from the duck song
why: in the first song the duck annoys the man in the lemonaid stand and eventually makes his day. so they become freinds. in the 2nd song the duck meets the corner store woman and annoys her. but makes her day miserable. and in the third song the duck leads the lemonade stand man to the corner store woman. and which they fall in love
in the poopers the magic penguin side song which is after the third duck song he makes a scenario where the lemonade stand man helps the kitten of the corner store woman which causes her to finally fall in love with the lemonade stand man
to summarise it all up.
the duck helped the lemonade stand man get a girlfreind. what a legend
