Beep & Boop?
Little is known about these bird people. The following is the only description we have of them.
Beep beep boop. Beep. Beep boop. Beep & boop, beep boop. Beep boop. Boop Boop. Beep boop beep. Boop! Beep beep boop beep boop... Beep boop, beep beep boop. Beep boop. Beep. Beep boop beep. Beep & boop beep? Beep boop. Beep boop beep...
One other important thing to note is that Rainy Day Betty is the only Wild Soul that can communicate with Beep & Boop. She spent a good portion of her 100-year education living amongst them and picked up on their tones and beeps. Only spoken, the written language still cannot be translated.
