Hamtaro: Ham-Ham Heartbreak[]
May 3, 2002
Hamtaro
Zelda
There's a part in the game where the player goes to Sunny Peak and pulls The Legendary Spoon out of its pedestal, but to do so three marbles are needed: a red marble, a blue marble and a green marble. This scene parodies the scene from The Legend of Zelda: A Link to the Past where Link pulls the Master Sword from its pedestal, after bringing a blue, red and green orb to it. The pedestal is almost identical, the spoon's handle is shaped similarly to the Master Sword's, and the same jingle of Link taking the Master Sword is even played when spoon is taken.
An additional reference was added in the international version of the game, where one of the Ham-Merchants across the game says "Buy something, will ya?", referencing the line from The Legend of Zelda "Buy somethin' will ya?"
