“That’s more a feature than a bug 
By using a specific text as an input you can produce a text sounding like the input. E.g. texts in old English or try poems etc.”
Yes, that is a fantastic feature. If you start talking to Kooky in other languages (German and Danish are the ones I know about, there are probably others), he will reply in that language. You never see these languages show up in English channels simply because there are no relationships with the foreign words (apart from a few exceptions - die, bin in german etc).
