The Legend of Zelda: Ocarina of Time

The workers on Lon Lon Ranch, Talon and Ingo, are based on Mario and Luigi, heroes of the Mario series. The colours of Ingo's overalls seem to be based on Luigi's overalls from Super Mario Bros. Talon's daughter, Malon, also seems to resemble Princess Peach in some ways, such as her hairstyle.

If you look closely at Malon and Talon, you can see that they are wearing brooches featuring the face of Bowser, the villain from the Mario series.

When you enter Hyrule Castle's garden, look through the windows on the right-hand side and you can see pictures of characters from the Mario series: Mario, Yoshi, Peach and Bowser.

The first mask you receive in young Link's trading line is the Keaton Mask. This yellow mask with pointed ears is said to be popular with children in Hyrule. The Keaton Mask appears to be a reference to Pikachu in the Pokémon series.

When you finally meet Keaton in Majora's Mask, it appears as a ghost fox (kitsune), which was the inspiration for the Pokémon Vulpix and Ninetales.

In Dodongo's Cavern, climb up to the second floor and look out over the main entrance. There is a sign here written on a stone tablet rather than a wooden signpost.

This tablet was first seen under the star-shaped fountain in Peach's garden in Super Mario 64, reading "Eternal Star". However, due to the low quality of textures on the Nintendo 64, the sign became the subject of rumours that it actually read "L is Real Star 2041" and was part of a method to unlock Luigi.

The Stone of Agony is shaped like the Nintendo 64 Rumble Pak. Once you have it, you can detect nearby secret holes in the ground if you have a Rumble Pak connected.

While not available through normal gameplay, one of the enemies that was programmed into the game is an Arwing, one of the fighter planes from the Star Fox series. It has so far only been unlocked using a Game Shark code.

The Arwing flies around shooting lasers at Link. If hit with a weapon, it spins around and crashes into the ground, causing a damaging explosion.

When you enter the Hyrule Castle garden where you first meet Zelda, look through the window on the right. The room inside contains blocks, pipes and a background design based on New Super Mario Bros.

This replaces the Mario picture cameos from the original game.

Most of the interiors in the game have been redesigned. Inside the Happy Mask Shop in Hyrule Castle Town as Young Link, there are shelves covered in masks. All of these masks were originally found on the Happy Mask Salesman's backpack in The Legend of Zelda: Majora's Mask. You can even see the backpack hidden behind the Happy Mask Salesman.

The Mario mask from Majora's Mask is just barely visible behind the mirror in the shop.

Hidden in the game are three pieces of artwork from The Legend of Zelda: Skyward Sword, a future title at the time of this game's release. All three depict Link slashing his sword in different poses.

• Bombchu Shop

  As Young Link, go to the Bombchu Shop in Hyrule Castle Town at night. Speak to the shopkeeper and scroll over to the left to see the first picture.

• Lon Lon Ranch

  As Adult Link, head into the house at Lon Lon Ranch and go up to Ingo's bedroom. To the left of the door are two pots. Break them and you can see the second picture leaning against the drawers.

• Gerudo Fortress

  As Adult Link, go to the Gerudo Fortress jail where you are thrown when captured. Hookshot out and jump across to the platform on the left where you can see a door. Go through and follow the corridor to a room with two Gerudo guards. Break the crate in this room to find the third piece of artwork.
