Definitely something interesting. Adds some meaning to the game title and I believe that once the new world generator starts working correctly, hopefully, biomes will not be separated by bridges, but a whole continent fill form ( heck, there can still be lakes and seas ). That would imply that choosing the best suitable location for your big camp will be quite important.
Spoiling will definitely add a bit of difficulties for explorers, but I believe that this game should do just that be more and more difficult.
Also, it adds meaning to the tent as well, not just for fun but for strategic switching when needed, which is merely awesome.
The pumpkin dog thingie seems like a swamp creature to me, that could be hostile if you do not posses the Boned Eye XD
