In some games, you get a dog companion who follows you around and sniffs out treasure. I think I first experienced this in Secret of Evermore and most recently in Dragon Quest Builders 2.

Now that I’ve spent a lot of time walking a dog in real life, I want to make a game with a dog companion who sniffs out treasure - but half the time, instead of finding treasure, they eat something off the ground. You can’t see what it is, but it has a 25% chance of inflicting a random status ailment.
