Hot Cogs

Hot Cogs, or Peach's Castle-3, is the third course of Peach's Castle. It is unlocked from completing Magmaw River Cruise and its own completion unlocks Current Event. Its name is a pun on "hot dogs".

Layout
Luigi starts in a lava cave with a gear turning clockwise. A Lava Bubble is jumping around the gear. Another gear and Lava Bubble appear. After some distance, Luigi will encounter a Goombrat and the second Star Coin below. Another Goombrat, more Lava Bubbles and gears and a Red Ring follow. After a Goombrat, a few more Lava Bubbles and six more gears, Luigi will reach the Goal Pole.

Star Coins

 * Star Coin 1: At the very first gear, wait for it to rotate a bit to reveal the first Star Coin.
 * Star Coin 2: After the second gear, head to the area below the arrow sign and continue moving right. The Star Coin is located over a gear, almost completely submerged in lava.
 * Star Coin 3: Luigi must be Ice Luigi. Then, when Luigi encounters the third Goombrat, he must use Ice balls to defeat the Lava Bubbles, accessing the Star Coin.

Luigi Sighting

 * When Luigi reaches an arrow sign, he must break the hidden Brick Blocks to reveal a crouching 8-bit Luigi.
