That's amazing! VB Wario Land has amazing sprites and animations. Such a shame it was stuck in monochrome VB hell! But not anymore it seems! It actually makes wanna play it again.
Just found out there's a JavaScript version of SM64 available on the Scratch website for whatever reason so I decided to 31-star speedrun it just because I can. Though I didn't record it nor time it.
This probably not canon and just a texture they slapped on the coin because didn't feel like making a custom one. Kinda like a Shiver Star has the Earth map texture though it did spark quite a few theories.
