You get 7 Thistles. But it's basically impossible to avoid surfboards getting placed, no matter what you do, and if too many surfboards get placed, the Thistles will eventually start getting crushed and you have to PF them. With 16, I could beat it with some luck. With 21, I had to use power-ups to beat it.
