If you were to change it to make it look like it came from a magma cube, then it wouldn't look like you could make it with a slimeball and blaze powder >_>
So what? It certainly matches. I think of magma cubes as slimes that fell into magma. Magma Cream appears to be the cooled-down version of a magma cubes form. :tongue.gif:
I meant that now the primary source of magma cream is magma cubes, which have no resemblance to the current tecture.
I doubt they'll change it at this point, you could always make a texture pack and change it yourself if it bothers you.
