Blobs are cute and all, but how about we add blurple blobs too?

Describe the solution you'd like
When purchasing blob skins from the shop, there is a 1/1452 chance that it will be a blurple blob skin instead. This is permanent.
For team modes, we're just gonna have red, blue, yellow, and green blobs instead of yellow vs. blurple blobs.

Describe alternatives you've considered

1. When you spawn, there's a 1/1452 chance that your blob will spawn as a blurple blob in FFA. As long as there is at least one blurple blob in the room, blurple brick walls for blurple blobs to hide behind will appear.
2. Blurple blob skin variants can be purchased at 4x the price.

Additional context
We're gonna need to make a lot of blurple blobs in the future...
