Zac is one of my nephews, super small but it's like he's made of elastic, all lean, flexible muscle.
He's always been a tiger kid, he's had a floppy tiger toy since he was very young, but I've just discovered that he loves sugar-gliders too.
He's into Ninja, and is pretty good at it, so strong and agile and he doesn't weigh anything. I feel like he's a sugar-glider at this age. Let's see if he becomes a tiger later...
