Trying too hard
Kids like funny voices - it has been proven. That is what Egoraptor is all about. Making funny voices!!!! And is it ever hilarious!!!
Egoraptor has always tried too hard and it is this endearing quality, like the nerd who can't get a girl til' the end of the movie, that has made him a success. With his funny little voices (that all sound identical) he has churned out more crap on NG that has been praised by the shut-ins as complete gold!!! Why? Because they can relate to his trying-too-hard approach.
Great "voice acting" by the way!
