Tropwen

Overview
Tropwen is known as the birthplace of Dunderland, as this is where the first city of Dunderland came from. However that was centuries ago, and now is a vicious jungle of broccoli, and hold the portal to the Broccoli Realm. To most alien life-forms, this place is even worse to crash your ship on than a black hole, as in a black hole you at least have some chance of re-appearing in a non-hostile dimension.

History
Nobody knows how old Tropwen is, nor exactly how many years ago it was that Dunderland I was made. All that is certain is that when Dunderland IV came around, the planet slowly lost trading business and the population left it behind. However, when Nonotron came into being a temporal rift opened on the surface of the planet, which led to an alternate reality - the Broccoli Realm. This caused wild creatures to escape into the Dunderland Empire - most of them could be handled with ease - and it brought much confusion to the Guild of Science. This problem soon became everyone's problem as reports of broccolictic forests began to increase in all sorts of locations, and the planet Tropwen was the source of it. Whatever has happened to this planet has affected the entire Omniverse, as the Broccoli Realm is spreading everywhere since the opening of the rift.
