Don Robinson, who had been partners with Hick in opening Flamingo Park and Cleethorpes etc. left the company (Associated Pleasure Parks) and subsequently set up Scarborough Zoo and Marineland. When Hick sold out to Scotia in 1972, Don Robinson rejoined to head "Scotia Pleasure Parks" which then embraced the AAP outfits (Cleethorpes, Flamingo, Knaresborough etc.) plus Dudley Zoo and Robinson's own venture in Scarborough.
Flamingo Park opened on 28th June 1961 and, as John says, acquired Dolphins in 1963. Don Robinson was also a former wrestler. I believe his wrestling name was "Dr Death" (not sure if it was the abbreviation or the full "Doctor"). I think he had been a Rugby League player on the books of Hull Kingston Rovers too. Of course he eventually had spells as the chairman of both Scarborough and Hull City football clubs.
