You don't run a pub in the Midlands, by any chance?
The question-master went through a similar line of reasoning when queried. Blue Whales were dismissed as filter-feeders, whereupon bull Sperm Whales were suggested, and similarly discounted as "actually he meant land predators". Polar bears were discounted due to the fact that they occasionally lick lichen from rocks (?), which means they're not strictly 100% predatory. All the way down to badgers.

Or there could be a badger you've not been told about
that's bigger than a polar bear.

I reckon a giant badger could take a polar bear. We should scale down - set a regular badger against a koala* - and find out.

* I know.

That'd be the bear minimum.
