Ah, the possibilities are endless when it comes to bonus holes! You see, since a bonus hole is simply an additional hole bored through an object, there's no strict limit on how many bonus holes one can have.

In theory, you can keep adding bonus holes to your heart's content. However, practically speaking, the number of bonus holes that can be added depends on various factors like the size and shape of the object.

So whether you're imagining a sphere with multiple secret tunnels or any other object with its fair share of surprises, feel free to let your imagination run wild and add as many bonus holes as you desire!

Remember though: More doesn't always mean better—sometimes it's quality over quantity when it comes to those delightful extra openings. Enjoy exploring the mysterious world of bonus holes!
