It is Xela's Hatchday (Birthday)!
Kaz wanted to do something special for her, so he took her to the beach and met up with Xela's dolphin friend, Nelly.
Xela and Kaz were having some fun in the water while Nelly was relaxing on the beach. Then Kaz saw something swimming in the water, so he sicks his head under the water to see what it is. Xela giggles when she sees Kaz's big, green butt sticking out of the water, but then she sees a fin rising out of the water, think it was Nelly for a second but then she sees it's a small shark. And Xela hates sharks.
Kaz, still with his head under the water suddenly felt something heavy land on his back. He lifts his head out of the water to see Xela on his back, shivering with fear. Kaz sees some more shark's appear, swimming around then both, clearly not a threat to them but Xela still doesn't like them either way. Kaz finds it really funny that Xela is scared of these cute, little guys and that Xela is holding on to his bum cheeks for safety. Nelly also sees what's going on and starts laughing as well.
Kaz then starts to tease her by slowly lowering his rump into the water but Xela digs her claws into his bum cheeks and tells him not too.
After a few minutes, his decides to walk out of the the with Xela still on his back and let's her off. Kaz apologised to her and she was ok with it, she said she would get him back at some point.

Happy Hatchday Xela!
