OK, if that's the case then yeah, the pages should be renamed. The -ler thing sounds like theme naming and yes it should be retained whether we translate them or not. If definitely looks like we have some bad translations on Category:Vader_Monsters. Such as Tayajigolar (Tire Monster) - Taya is a clear case of katakana being used, so the jigo part hasn't been translated at all there as far as I can see. Add Nihongo templates if you can please.

It looks like the names are consistently Japanese unlike some later seasons. With the -ler endings too, I'd say stick with Japanese for the page names. The -ler thing on English names, as in the example you cited, is definitely Engrishy, since Squirrel is a noun, not a verb. Jigo is a distortion of Jiko that means "Accident" (as in Road Accident)
