Habitarium Goodies Chest was awarded to those who helped Professor Clodbottle eliminate all the petpets in the Habitarium prior to it shutting down. This was a way of thanking the users, and can be received by visiting this link if you haven’t done so yet.
Inside this chest, you will find these six items:
Six-sided Die
Tiny Giant Squid
Water Droplet
Cheese Crumb
Mini Meatball
Snowpetpetpet
The Habitarium Goodies Chest are currently selling for around 500,000 NP, so it might be a better choice to hold onto the bag rather than opening it. As the items on the inside have no real value.
For those who were wondering on the rather strange art of these items, it is because these are items strange from the Habitarium.
