So in the beginning they try these three fish and squid paste based Taro snacks made by a company called Kaedo. The flavours are 焼肉 カルビ "Yakiniku Karubi" or Korean short rib barbecue, たこ "Tako" or octopus (quite vinegary) and わさびのり"wasabi nori". They are a favorite among Japanese children, but would most likely put off anyone with their weird, slimy chewing candy texture. That aside, I thought the way Becky described the octopus one "eww smells fishy and vinegary" would actually appeal to her, given that Big Al's FUPA and other nether regions are her usual snacks of choice and - wait this is not the nasty thread now, apologies dear farmers.
Next we have a package of Ramen Ya-san dried ramen noodles snack. These are delicious, very flavorful and similar to the ones they eat later (Yatta-men).
The medicine looking candy are プチプチ占いラムネ or "puchipuchiuranai ramune" a ramune soda flavored candy which also helps you find out your future, or so it claims. Each candy is associated with a part of your life - デート "de-to" or dating, しゅみ "shumi" or hobbies and so on. Underneath each candy there is a ◎ which means great, ○ which is good and x which is bad, signifying how your year is going to go.
The jello is probably Sakura flavored Konnyaku or Konjac jelly, very subtle flavour so no surprise that they couldn't even taste it properly.
The following one that neither of them liked is not chocolate, but dehydrated sour plum or "umeboshi". Its my absolute favourite thing in the world, salty, sour, sweet - I guess one of those things you can truly describe as umami.
Next we have another Ramune Soda flavoured candy, Kuppi. Fun fact, "ramune" actually comes from the Japanese pronunciation of lemonade. That's why it is such a popular flavour, especially during summer time.
The gummy is cola flavoured Maken candy, in the shape of rock-paper-scissors.
The Marukawa gum triggered me so much. First of all, its supposed to colour your tongue in whichever colour the packaging is. It literally shows on the packaging (see for yourself). But they're only chewing one dainty little corner and spoiling the fun. I was really looking forward to a black or blue tongue binge monster...

as far as I remember, red is cola, blue is soda and black - grape.
The matcha KitKat needs no introduction, but the fact that she didn't even snap it, just bit into it directly was...ugh.
And so was both of them licking that poor Fujiya pop-candy grape lollipop... What did Peko-chan ever do to you?
And who the hell tries pop-rocks one by one? Is this for real?
This comment is getting quite long already so I'll just simply list the rest of the treats:
ハイチュウ "Hi-chew" green apple chewing candy.
Heart shaped hard candy. (There are so many brands which do big bags of confectionery sweets that it's hard for me to tell which one are these part of)
Yaokin Sour Grape Gummy.
Manekineko golden cat hard candy. (Loves Japanese culture but doesn't even know what that bloody cat is called)
Blue star shaped hard candy. (ditto the heart one)
Super Mario Bros Gum.
Chirin Ramune "Kanpai" candy.
Mini Cola (red) and Mini Sour (blue) candy. And no, none of these last ones need to be mixed with water, but ofc...bunch of picky eaters these two...
