A literal jungle gym
Because Regulus absolutely refuses to touch his weird muggle computer (social media doesn't really work for a boy who dislikes being social,) but all your characters would likely notice it in game:
Annoyed with the spider bouncing, Regulus cracked his neck like a bamf and used a combination of herbology and transfiguration magics to heighten the growth of some of the plants in the area to make a living, eco friendly jungle gym.
It looks much like this:
And has broad runged ladders/monkey bars at an approximately 45 degree angle at a couple points to make it easier for other people who are less web shooter inclined to get up on it.
It's also minus the tires.
He spent a while working on it so if you'd like to have a mental note that your character saw this tiny wizard boy doing a thing, feel free!
It's open to everyone, Peter Parker or not. Peter was just the reason he started doing it. I know Gwen will likely be on it soon in their thread and I'm absolutely sure that Dick is not gonna be able to resist being a Flying Grayson.
