sniffers can be introduced to new plants

Sniffers only have 2 plants they could find so far. I am sure Mojang will add more, but there is another cool feature they should add. The sniffer is ancient, so it can only find plants it remembers. However, it should be able to discover new plants as well. To introduce the sniffer to a new plant, it should have to come within a block of the new flora. The sniffer should act confused for a second, sniff the air a little bit, and then sneeze. Maybe afterward it would lick the plant and maybe eat it. After learning the scent  of a new plant, the sniffer would occasionally dig up that seed as well. As a price to pay for the sniffers new ability, the sniffer could also over excitedly dig up your crops.
