Dino Piranha Speed Run

Dino Piranha Speed Run is the fourth mission of Good Egg Galaxy of Super Mario Galaxy. Mario (or Luigi) must complete a slightly-different version of the Dino Piranha mission under four minutes. If Mario exceeds the time limit, he loses a life. This mission can be played only once a Speedy Comet is orbiting the Galaxy. The comet has a chance of appearing only after Mario collects the thirteenth Power Star.

Layout
As the original mission, Mario lands on the starting planet and is allocated four minutes. The goal remains the same: Mario arrives to the top of the structure underneath the planet, but instead of having to spin to open an Item Crystal containing a Luma, the Luma is already there and transforms immediately to a Sling Star as Mario talks to the Luma. The Sling Star launches Mario to a Launch Star that launches Mario to the boulder planet, this time featuring Chomps as opposed to Boulders. The goal also remains the same here: Mario collects five yellow Star Chips that form a Launch Star, which takes him to the bean planet. The bean planet also contains the same goal as before: defeating the Piranha Plant spawns a Sproutle Vine. Using the Mario Sproutle Vine, Mario lands on the bitten apple planet. Even here, Boulders are replaced by Chomps. Defeating the Prickly Piranha Plant spawns a Sproutle Vine. This Sproutle Vine takes Mario to the block-climb planet. Mario can alternatively defeat a lone Piranha Plant atop a Warp Pipe to access the flipswitch planet, which he then navigates by activating all Flipswitch Panels found there until a Launch Star takes him to the block-climb planet. Mario then navigates the block-climb planet, destroys the Item Crystal containing a Launch Star, and travels to the dino geo planet. Dino Piranha is fought using the same strategy as before: spinning four times at his tail defeats him, revealing the Power Star. Grabbing the Power Star stops the timer, ending the mission.
