Kiddy character who is still unnamed. It was Li'l Wy (after my nephew wyatt) but then my sister had another kid, and I didn't want to play favorites with the kids

I wrote a short story (kid's style) for my nephew, at least a year or so ago. We spent a day at the park near my apartment, and Wyatt turned the whole playground into one giant adventure land, and between him and duke running up the ladder and going down the slide, they inspired the story. Unfortunately, all I ever had time to do was draw a few character sheets, though, and it got put on hold for school.

Are they still called jungle gyms, or am I still just that much of a 90's kid? XD
