#1: Sea Wees. Fortysomething female friends, please tell me that you remember these toys, initially released in 1979. BECAUSE THEY WERE ALL KINDS OF AWESOME.
And then, at some point, they started to release progressively glittery versions - very space mermaid-ish, actually. They were Celine before Celine was Celine.
And that's all I have to say about mermaids. Which is surprisingly more than I ever thought I would say in written format.
Carry on, and enjoy your day.
