Cogs are collectible items in the second game. There are four cogs that can be found, and they are connected to primary events, making it obligatory to find them in order to progress in the story. Every cog is used at least twice in the game, forcing the player to backtrack to get back every cog for the Tiny Tomba/Mini Tomba event.
List of cogs[]
Star-Shaped Cog[]
Found on the fish drying net in the Town of the Fishermen. It is used for the Wind it Up! event. In order to obtain it, the fish drying net must be raised using the giant lever beside it.
Hexagon Gear[]
Found inside an ice block in Kujara Summit. It is used for the Raise the Ladder! event. Use the Fire Hammer Tomba obtained from the Bring the Big Sack! event to melt the ice block.
Triangle Gear[]
Found in the Circus Village and obtained after the Use the Seesaw! event. It used in order to extend the bridge in the town. Fetch the circus ball, lead it to the seesaw and smash it with the hammer to make it fly up to the second floor. Repeat this on the seesaw there to knock down the bird holding the gear in order to obtain it.
