Hey there @LittenTheDragonSin, the Blue Pixpet Bed can normally be bought from the Gateway City Store in the main plaza. The catch is that it can only be bought once per adventurer, and unfortunately if you exported it, it can't be brought back into the game. So your only option is to put a different pet in the adventure (basically like starting a new game) and re-buy the item from the store. Sorry about that! :s

Please let me know if you have any further questions!

Hmmm odd. While the bed can be found via hoarding, you wouldn't be able to import it to the adventure. As far as I'm aware, the only way to get it within the adventure is how I mentioned, but if you ever find it again a different way, I'd be really interested in hearing about it. :o
