Raw source: [\#539003](//www.nyaa.se/?page=view&tid=539003) Too lazy to translate the reference explanations at the end, so here are just some essential points: 1\) The song she's singing at the beginning is one of the Sazae-san theme songs. 2\) Read about Glico caramel and toys [here](http://www.glico.co.jp/en/corp/glicoway02.html). 3\) Hato no Oyomesan is a comedy manga series (which also got a flash anime adaptation by DLE). 4\) PGP = Panda! Go, Panda! (a classic animated film).
