Double Rainbow 'Perfectly Pumpkin' ice cream tastes almost exactly like Japanese yuzu air freshener smells. With every mouthful I'm flashing back to trying to take a shit in the Japanese-style toilet on the shinkansen to Osaka.
The finish, on the other hand, is more like a Little Trees™ Vanillaroma™ car freshener. However, it is emphatically not as fresh as a breeze; it's more like a smack to the back of your throat.
