Maybe you could go for words ending with "-berry" and spell it "-beary"... like "strawbeary", "raspbeary" and so on...? Oh, and words with "-brary" as well...e.g. "libreary"! *lol* I'll list some more that just popped into my mind:
delibearate/ not delibearate
bearable/ unbearable
Bipolar Bear One/Bipolar Bear Two
Growling for Columbine
Growling Ally
...or some combination with "karu" (which is Estonian for "bear"
) ?
