Dr. Dougal's Cure All Advice

For the sniffles
Take a Nap and eat some sardines.

For a cough
Take two naps, have some sardines and then cuddle up for another nap.

For a fever
Find some sunshine and a comfy couch. No sardines. Wait for the fever to pass.

For broken bones
I have no idea. I've never broken any bones (mine or someone elses) so . . . you're on your own.
