Your welcome. As for the Pick Shark you do not need the breed it with just the orange shark. You can use any different breeds to end up with the Pink shark. As for the eggs they will at some point produce the Pink shark.

I started a new game and went for the magic fish straight away, and i got lucky and got the Pick Shark in my first bunch of "unusual eggs"

If you have any more questions feel free to PM me or leave a post here.
