This title is included with every new Wii console. The offering on this page is meant to be a replacement or an extra copy. Replacement disks can also be ordered directly from Nintendo Support by calling 1-800-255-3700.
It's worth a try, or you could get a used copy for $18 + $4 shipping.
When you say 'destroyed' do you mean really scratched or actually broken? If it's just scratched you might be able to have a store near you that does disc resurfacing (or do it yourself).
