What I think is a very key difference between this and some of the other similar pours that have been done is that marble cake is very much a cake, and this dildo is also very much a cake, and so a marble cake color on a cake dildo is something that would be very easy to think of, especially if you are a fan of marble cake (as any cake fan should be)
A cake color on a cake dildo is very sensible and aesthetically pleasing.
This is very different from a random toy having the same color as an established toy for no determinable reason, especially when the place without a determinable reason has been known to steal ideas in the past and has not ever stopped.
