From the Super Mario Wiki
“May the pasta be with you.”
Obi-Wan Toadi is a bearded Mushroom space colonist, who appears to run the Mushroom Colony, which is located on a desolate, desert-like planet. Obi-Wan Toadi only ever appeared in The Super Mario Bros. Super Show! episode "Star Koopa". He is a spoof of Obi-Wan Kenobi from the Star Wars series. His quote, "May the pasta be with you," is a pun on the quote, "May the Force be with you" from the same series.
When Mario, Luigi, Princess Toadstool and Toad arrived at the Mushroom Colony to try and save it from Darth Koopa's Birdo Ray, Princess Toadstool explained to Obi-Wan Toadi that they only had fifteen minutes left before the planet would be destroyed. Although Obi-Wan Toadi concluded that there wasn't enough time to fight back, Princess Toadstool begged for Obi-Wan Toadi to find a way. Obi-Wan Toadi explained that Mario's group would have to penetrate Koop Star in Mushroom Starfighters, so that someone could disable the Birdo Ray. Mario agreed, under the promise that he would be fed lunch afterwards.
Before Mario took off, Obi-Wan Toadi could sense that Mario was nervous, and presented him with a pizza to bolster his spirits (as well as his appetite). After saying "May the pasta be with you" to Mario, Obi-Wan Toadi saw Mario and his friends off, as they flew into space to take down Koop Star.
After Mario and his friends completed their mission, Obi-Wan Toadi, along with the rest of the Mushroom space colonists, congratulated them all upon their return. Mario, however, was more concerned with the lunch that Obi-Wan Toadi had promised him, causing everyone to laugh.
