You are a Pokémon (of your choice) who lives in the forest, one night, You awaken during the night, feeling thirsty, you head out for a drink of water, As you drink, you notice a canister glowing beside the water, you are curious. You slowly move closer and closer, your curiosity increasing, you tap on it (or swat it), which makes it release a gas that you inhailed (for as long as you put it), you leap away in fear, back to your pack.
