Sometimes when entering as Chang, you will be fluffed and spawn in the sky. This only happens in the Dreamcast version.
In later builds of the Dreamcast version, the ship lacks cat scratches to reach the upper area with the Energy, Thermal, and Smart, despite being present in earlier builds and a prototype of the game. Despite this, it's still possible to get up there using Bungalow.
To get up there, go to where the four pipes where Bungalow and Chang's telepoints are. At a certain angle and standing on the mini railing of that area, you have to jump up the shorter pipe from the back (somewhere between the back and side) and repeatedly mash the jump button while continuing to move forward. If done correctly, Bungalow will jump a second time and get on top of the black/red hexagonal pillar. Once you are at the top, jump to the top of either of the taller pipes, get to the highest angle possible (dead center), and run over and jump right when you reach the edge. If done at the right height and at the furthest point you can jump, you will make it to the aforementioned upper area. See Gallery for a visual reference.
In Viggo's Revenge, when leaving the hub world for the first time and returning to the village, you will instead emerge out of the gates to the City of Fear. This can be confusing for first time players as they may not know how to return to Viggo A Gogo due to not seeing the exit.
