Frozen Party at Lawson This Summer

Hah, not the animated movie, sorry.

Frozen Party is the funny name of some Machi Cafe treats I just noticed in a Lawson. They are sort of cup parfaits or frozen smoothie looking treats. The flavors look so weird too. There are typical flavors like strawberry and then "Go Go Let's Go Mango" as seen below.

In the weather series you can choose from rainy or sunny soda. These have something at the top that looks too much like duppogi / mochi or cheese. Not sure what it is.

I'm kinda tempted to try this almost disgusting sounding Cheese Macha flavor.

These Uche Cafe ice cream bars look so nice on the other hand. Especially the ume flavor. They are also about half the price and seem to contain real food.

Alas, frozen things was not the purpose of my visit.

What should I try?  I think I wanna test out a frozen party this weekend.
