Curiosidades

Miklos Perlous, the voice of Eric, wrote at least two episodes (both in the last season) one of which was "Graduation Daze".

The 2005 YTV Funpak shorts had a few different voice actors than the TV series: Eric was voiced by Peter Oldring instead of Miklos Perlous, Vana and Kitty were both voiced by Stephanie Beard instead of Stephanie Anne Mills and Denise Oliver respectfully, and Professor Pamplemoose was voiced by Alex Nussbaum instead of Patrick McKenna. Only a few voice actors from the shorts returned to their roles.

Trevor Troublemeyer, Eric Needles' best friend, is said to be co-creator Todd Kauffman's favorite character.

Todd Kauffman has shared early concept art for the characters through his blogs and social media, revealing a number of design differences that were not present in the Funpak shorts.

• Maxum Man was originally named Mega Man, but it was changed to avoid confusion with the other, better-known Mega Man. Also, his chest emblem had two M's instead of just one and he had a narrower head shape.
• Early designs for Eric did not incorporate the so-called "Neptoon Skull" (the same stylized skull seen on Duncan's shirt in Total Drama and Corey's hat in Grojband), with the character instead wearing a formal uniform similar to that of Kitty. He also had a much larger, rounder head, with a much longer, curvier nose.
• Trevor's dad originally wore glasses and had a white shirt instead of a blue one.
• Kitty was going to be the main protagonist instead of Eric as she wears a Maxum Man outfit.

In the US, Cartoon Network only aired the first two seasons of the series during its 2011-2012 run on the channel, with Qubo airing the remaining last season five years later in 2017.
