Wikisimpsons - The Simpsons Wiki
Texxon is a gas company in Springfield.
History
It had many branches in Springfield but it sold its branches to a frozen yoghurt company.
The company was running a promotion for The Happy Little Elves. There was a rarer elf, the Baby Musthave. These were obtained when you bought 10 gallons of gas from a Texxon gas station.
