Flame of Tomorrow

The Flame of Tomorrow is a treasure in Pikmin 2 and is actually a container of "Bowser Breath" brand matches (referring to Bowser and his fire breath, Bowser being the main antagonist of Nintendo's Mario series), which roll around when the box is moved. In Japan, the brand is called "Sun Breath" instead. It is found on sublevel 4 of the Citadel of Spiders, occurring in one of a few specific places, such as in an alcove or a pipe. A few Hermit Crawmads and Water Dumples may get in the way, so make sure they've been defeated before retrieving the treasure. One side of this box states "TEL 555-TROOPAS". It is tied for the least valuable treasure in the game.

Trivia

 * "TEL 555-TROOPAS" is equivalent to "555-876-6727" and is not a real, existing phone number; the telephone number prefix "555" is intended only for directory assistance in the United States and for this reason, it has been used for fake phone numbers in media.
 * In Japan, the phone number is instead 090-1234-5678 and acts as a phone number for the Sun Breath company.
 * Olimar's notes here suggest the Eternal Fuel Dynamo may not be as inexhaustible an energy source as the name implies.
