Relics are three items that are collected throughout the first half of the game to allow the player to get on the boat in the Dock level.
The compass is the first relic collected. It is found next to the Animal Ark in the Blacksmith level.
The Wheel is the second relic collected. It is found in the Lava World level, right after the Dragon and Sock Puppet boss.
The Telescope is the third and final relic collected. After defeating the Industrial Machine, the player will look through the telescope to see the Blue Princess being held captive.
