An overachieving student. A cute little lad/lass who gets frantic when they are late for class. A beluga is sure to put homework first and often get emotional about homework.
Kendrick: "Awww! Look at Alie running to class!"
Marlo: "She's such a beluga!"

Andrew: "Lets talk about homework and teachers and stuff! Omg!"

Kendrick and Marlo: " Aw Andrew you're a beluga!"
