Grown-Up Dynamo

The Grown-Up Dynamo is a treasure in. It is a big, red and silver-colored with the word "HIGHPOWER" written on it. It is about three times the width of Captain Olimar, about the same height as him, and is the same size as another fat battery treasure, the Rarely Seen Cell. Despite "Highpower" being a company in the real world, the battery does not resemble any product that that company sells. It can be found in the Crystal Tunnels area.

Collecting the treasure
Right after the crystal headbutt cutscene, the player can see the treasure above them. In order to retrieve it, Olimar just has to climb up a vine, without destroying the crystal standing before it. If the crystal is destroyed, the player can still get to the treasure with the jetpack, although it will be more difficult.
