Japanese festival food: Chu Chu pudding

My family and I have been seeing "Chu Chu pudding" food stalls at festivals around Saitama Prefecture the last year or two. My kids have ordered it before, but I didn't try it. But this past week, I tried one of the pudding flavors. I didn't buy it for myself, my husband had bought it for two of my kids at a children's day festival. However, regrettably, neither of them liked it and I ended up eating one of them.

Between us, we have only tried the pudding flavor one so far. Given the name of the product, I would imagine that pudding was the original flavor. But you can also get chocolate or strawberry flavors. Its pudding as in Japanese pudding - purin. Its served in a bottle suspiciously like a Kewpie mayonnaise bottle! So much so, I wonder if they use recycled Kewpie mayonnaise bottles.

Chu Chu pudding is served frozen in the bottle. So when you open it, it usually spills over straight away unless you put it directly to your mouth. Its a good concept and works as a street food - easy to eat on the move. But the price and flavor weren't to our liking. It cost 500 yen for one, which was overpriced in my humble opinion, especially considering that the taste was bland. 

I am sure that some taste better than others. There was no queue at the stall that we bought from. But we saw a queue at another chu chu pudding stand at another section of food stalls at the festival. Presumably, that chu chu pudding tasted better! Have you ever tried chu chu pudding? Did you like it?
