ok, so i beat the game and it lets you go back to any world you want. i was just randomly playing levels that i liked, and i think i was in world one, level four... you start out and there is this big coin that you can hit, then if you get all the coins a purple/ blue mushroom house shows up, and it says "hello! you found my shop of strange and wonderful things!" and there is only one box, when i opened it, what looks like an anchor came out. its silver. so, anyway, i'm wondering, what do you do (can you do) with the anchor. i've tried to use it, and it won't let me use it anywhere. its kinda like the hammer, where you can only use it by bricks that will break. any help/advice would be great. thanks
