Nice one thanks, and fully logical. (And educational too. Just been googling as I didnt get the link between the hippocampus in the brain and a seahorse. So I'vd just found it got its name from the greek words for seahorse, because of its shape. Think i'd prefer an actual seahorse in my brain!)

Thanks.

Huh, yeah, I didn't know that's where the name came from. Thanks to Bigmoose for posting this!
Anyway, nice puzzle, thanks!

Nice image but zero effort.

I liked this a lot. Thank you for a great puzzle!

Nice and totally logical - thanks :-)

Very well done. Logical with a great result. Thanks.

Thanks.
