After you defeat an opponent, sometimes they will give you an egg. If you buy the egg, after a short time it will become a frog. You are not notified of this, but if you keep checking back in Picwick, go to the Frogs section. The frogs you have hatched will be in there. Sometimes your opponents will also offer you items. Note: After defeating Sparky & Woosh 2, they may try to sell you some "Game Hints" book for 100,000. They will never offer it again -- it is recommended you buy it at that time if desired.
