It is a pleasant day and more so because you are taking a leisure walk in the forest full of birch trees. The greenery of the place and the unusual friendliness of the animals living here made the birch grove a wonderful place to be in. Now you want to get back home but you just cannot figure out the way to exit. You approach a fox staring at you and it offers you a deal – ‘Find 20 mysterious mushrooms and I will show the way out of the forest’. Perhaps, finding the mushrooms will be easier than finding the exit. You can already see few of them scattered around. You accept the deal and the rest is future.
