here's an easier-to-swallow translation:
Go to Booster's Tower and find Knife Guy. Play against him and win 12 times in a row. He will give you a bright card. Then go out to Bean Valley. At the part where there are 5 pipes in a circle, have Shy Away water the one closest to the save box. Battle him and go down that pipe. Battle the Chomp Chomp. At the lower left corner of that room, behing Chomp-Chomp, Jump there 3 times and jump on the new platform. Go through the passage and you'll be at Grate Guy's Casino. BONUS: Getting a star egg! Play look the other way with crate guy in the casino and win 100 times (he doesn't count losses against you) Throw away any stinky prizes, but keep things like Mushrooms, Max Mushrooms, and Royal Syrups. At the 100th win, he'll give you a star egg. This thing will do 100+ damage, no matter what! NEVER THROW AWAY THE STAR EGG OF THE BRIGHT CARD!! yOU'CAN NEVER GET THEM BACK!! Anyway, the egg's only worth 1 coin in the stores, while the card is 777 coins. ONLY SELL THE CARD IF YOU NEED A SERIOUS CASH BOOST AND CAN'T SELL ANYTHING ELSE!! You've been warned. Have a nice day (night?)!!
An extremly rare and valuable Yoshi!
