New Hybrid, a lovely orange striped shark. You get it, according to the screenshot I saw, by crossing a Thresher Shark and a Sabertooth Bunny. I know this is the same parentage as the Tiger Shark but perhaps one set of parents can have different types of children, either that or it is a glitch. I did have one person in the morphing tent swear to me that he used a Stormtiger shark so I don't have the proof yet. All my tries with both ways have only produced either of the parents. I will keep trying though. Out of gold at the moment so I am off to Aquila to chest hunt. I don't think I have the stamina for another Tower run tonight.
This can be something unique. In Wizard101, only certain designated pets can create one type of hybrid. Perhaps this game decided they will do things differently and allow pets to create 2 hybrids through one combination. However I would not be surprised if this was actually a bug.
