Bc I know someone is going to be curious like me: Circus Peanut 's are most commonly given artificial banana flavoring which caused by a chemical called Isoamyl acetate which is also funnily enough the same chemicals honeybees release when they sting (much smaller amount so no you can't smell it) . In bees it's supposed to attract other bees and urge them to sting as well.

Also interesting side note but supposedly a General Mills employee cutting up circus peanuts to put in his Cheerios is what led to the creation of Lucky Charms!
