The Animation is a HUGE improvement from your previous works, and bears a resemblance to Legendary Frog (god bless his soul) when he was still active in Newgrounds
The Idea is original, and as my fellow comrades stated, it can easily be expanded
Example: instead of school killing Chu, you other "students" join you to fight school and you make friends and allies. Professors can be the school minions etc.
The acting is much better then your previous work, still has that humorist tone that can wrap around your soul and gently give nudges and pulls to stimulate laughter,
For the following review i'll throw a 9
For Improved Acting, Visuals, and Creativity, and docking you 1 point for being too short RAWR! we want MOAR!!!
