Hmmm...well...Spike reminds me of a dog...
In fact Don Bluth wrote that Spike was to some degree designed after a dog he had known. Bluth wrote an article about this in the issue of his "Toon Talk" magazine which dealt with LBT in particular.
Ok getting off topic here:
Actually...what's ironic is that there is already a character Spike in the Rugrats, who is indeed a dog and doesn't talk obviously...

: but he talks in one of the movies, it was a cross over between the Wild Thornberrys and the Rugrats. They are similar in some ways....
But yeah, nice observation and info Malte.

On-topic: Oh yeah...Mr. Three Horn reminds me of a few conservatives I know

and Pterano reminds me of a cousin's dad who was immature and a liar

I feel bad for my cousin because of this

But Pterano does remind me of every single scared, insecure adult that's out there....
