Yup. We went to the local garden centre to spend £4(ish) on the tube connectors as we needed one more than we had. Had a look around while there, saw those and realised Fwirl would like climbing on them and one could be a way between the two taller bins. The photos show we were right (she has climbed on the dragon too, I just didn't photo it).
I swear she's part squirrel with how much she loves climbing, but those are big, strong, too heavy to be knocked over and work well for someone as insane as Fwirl to play with
It meant the visit cost considerably more than £4 but it was worth it
