Doopidoo

The Doopidoos are a species of bird-like quadrupeds, named for the sound they make "Doopidoo". Superficially, they do not appear to be very intelligent.

Biology
The resemble a combination of two Earth animals, the extinct dodo and the extant camel, and for whatever reason have bowl haircuts. They are presumably herbivorous, what with the abundance of trees in their home dimension, so they most likely eat whatever fruit grows from them.

History
The first encounter of this species was made by human scientist, and former terrorist, Rick Sanchez and his grandson Morty Smith, when they passed through their home dimension in an effort to shake the Council of the Ricks (a federation of different versions of Rick throughout the multiverse) off their tails.
