No best animal as others have said, just what you like the best. Using a pastel male, if you can afford a bumble bee female you can make killer bees or get any other double female with pastel in it (lemon blast, pastave, ...) that way you can make the super form of it. You may want to look at getting a different male as well, double males are as cheap as $350 for lemon blast or others with pastels in them. Good luck either way
