I am glad it inspired! I didn't spent a lot on anything. It is really just a hodge podge of stuff. I think that giant ladder was the most expensive because is was a total impulse purchase.
I forgot to mention the bamboo skewers. By sheer coincidence they fit perfectly through the whole we drilled in the play gym to allow me to zip tie things to the cross bars. I stick them through the holes and hang veggies and toys on them. They also like to perch on them sometimes too. The wholes are also the size to fit the screws on the branch perches you buy at the pet store. I was able to just twist that multi stemmed manzanita branch right into the existing hole. Unplanned flexibility!
