Vintage 1996 Trendmasters Star Castle Neptune under the sea mermaid castle

Vintage 1996 Trendmasters Starcastle playset. Missing accessories. Has bubble wand and tank. Different play features (shells that open etc.) missing some flags, some damage to towers. Discolouration from age. It is missing its key. It can close and be opened by using another object (like scissor blades, etc) I tried new batteries, but the light up feature doesn’t seem to be working. Sold as is. Still a really cool playset.
