Curry rice and shirotama. Shirotama got its name because it's a white (shiroi) ball (tama), but I'd like to see a shirotama that would lose this quality because of curry! That'd be Curry-tama (laughs)
Gummi candy and takoyaki ♪ If you replace the octopus with gummi, it should have a good texture (^ω^)☆
Avocado on top of rice with egg? I think there are already people who combine those though (laughs)
