The Sunspire why do piranha plant have bone in it?

Umi tilted her head. Then she tilted it more. And more.
What a weird looking animal.
She looked at his flexed paw. ...Weird, was all she could manage. A real photograph of what Benry was describing probably wouldn't have been any less weird for her. The strangest beast she had ever encountered had been a sea lion, with porcupines as a close second.

The lioness listened to the rest of his strange tale of falling asleep after being bitten by something, then waking up in this area. Her jaw was wide open at that point in disbelief. That's the craziest thing I've ever heard, she said. She could tell he was telling the truth despite its insanity. His nature was so bumbling and odd that she didn't believe him capable of making up something quite this crazy. Abruptly, she closed the distance between them and sniffed at his shoulder and side with hardly an inch of space. She felt her whiskers graze his fur. She did it to confirm he was actually a lion and not.. something else.

Umi stood back again, settling herself on her haunches. Weird. You smell like everyone else, she confirmed, rather puzzled.
