We've all done it in our childhood, playing doctor. Well with these Yogurette candy, this is even more real ;p
We saw that Dagashi in the episode 6 of Dagahi Kashi when Saya -chan remembers the time she came to play with Kokonotsu-kun. He showed her his yogurt candy box and present her their benefits for growing children. Then they played doctor and patient together, alternatively changing the roles of course, for everyone to pretend to take the candy as drugs.
At first, this candy looks a bit like candy necklace, it's almost the same texture. The only difference is that this Yogurette candy tastes like sweet yogurt.
