A man who's spent four decades collecting thousands and thousands of dolphin-related objects has let our camera crew into his home for the first time.

Michael Caine from Plymouth began his collection after a childhood encounter, and his "school" has grown from there...

10,500 dolphin related objects, from models to mugs

£91,000 estimated worth of the collection

I don't want anything else other than dolphins. Every piece of wall, anywhere around my bungalow, I'll put something else there... I've still got 30 boxes up in the attic that have to come down, but I am squeezing them in slowly. Michael Caine

His bungalow is home to dolphin figurines, stuffed animals, posters, plates, mirrors, models, and even dolphin-shaped light fittings.

His love for the sea mammals started when he was just seven years old - he was out canoeing when a dolphin started swimming alongside him. He got into the water and swam with the animal, saying he "fell in love" with them.

From there, Michael's collection has grown and grown - it now takes a cleaner a whole week to get through each room.
