Whackass dream I just remembered

I had a dream a while back I was playing a copy of Super Mario 64. It was kinda the same but there was an extra level in a snowy mountain top where you could stumble across a train that was aggressively Christmas themed. 

I didn't have enough stars to play it and I swear it had something like 60+ stars, but the outside of it looked so off, the train had this dark granite-marble texture with the roof texture off the top of Princess Peach's castle and whenever I turned the camera in the right way I could actually see the mini game the level had inside, which was a colouring game complete with these ripped pages off some kids colouring book.

I think the level was also on some kids book shelf at the same time with some toy blocks in the background, the sky was what really added to the creep factor, there was barely any stars (aside from the super stars that decorated the surrounding mountains as part of a festive garland*) and clouds ominously drifting about in the background.

*and no I couldn't grab them.
