How do I get access to the cannon outside of the castle?

Question

There is a cannon just outside of the castle in Super Mario Word 64 but it's locked ! It is near the water, on the beach. Can I get access to it ? If so, how ?

Answer 1

I believe you're talking about the cannon outside the castle in Super Mario 64 - this cannon will launch you up to a secret area, but only if you've got all 120 stars.

For getting all the stars and accessing this secret cannon:

Yoshi is up on top of the castle, and if you get up there, he'll hook you up with many extra lives :)
