How many shines do you need to unlock Pinna Park?

Excuse me, I was wondering if you could help me understand something. The game I'm playing has a feature where you need to collect a certain number of shines to unlock Pinna Park. Could you tell me, how many shines do I actually need to acquire in order to gain access to this park? I've been playing for a while now and I'm eager to explore what's in store there. Thanks in advance for your assistance.
