"I cannot believe it!!!!!"
— Quincy's most famous quote.

Quincy is the third member of the Little Einsteins team, and appears in two shows - Little Einsteins and Barney and the Rocko Squad.

He loves to play every type of musical instrument, the violin, the guitar and the trumpet being his favorites. He is the only member of the team who's afraid of the dark (as seen in the Little Einsteins episode The Northern Night Light and in Our Huge Adventure, which is a direct-to-video film starring the Little Einsteins). He may be of African American decent due to his dark brown skin and slightly Southern accent. He was named after famous musician/composer/arranger Quincy Jones. When he notices that Alisa Bosconovitch is fast asleep, his usual response is "I cannot believe it!", which is almost always pronounced as "I ... can ... not ... be ...LIEVE!".

In both Little Einsteins and Barney and the Rocko Squad, Quincy is voiced by Aiden Pompey.
