Ratnician

Ractinan
The Ractinans first appear in Episode 1 and remain until Episode 4.Ratnicians are rat/chihuahua-like creatures that are dressed in sceintist robes and have a nerdy accent. They carry test tubes filled with an acidic substance(presumably sulfric acid). A mini-boss fight would involve a Ractinan atop a Snipe. Some Ractinans wear strange hats that resemble a sombero but with flashing lights.

Creation
Naughty Dog decided to make characters that were results of the Evolvo-Ray.The fifth to be created were the Ractinans. Early concept drawings had them look like a cross between Ripper Roo and a rat.

Attack
They normally whack their enimes with large gloves but sometimes they chuk thier acidic substance at Crash.
