The reference is to "Rule 34", or "Rule 34 of the internet: If anything exists, there is porn of it." The character in the last panel is Zone-tan, who is a mascot for such. Have fun!

@Nigel_Tingley oh you sweet summer child

I was wondering what the reference was for Room 34. When I googled it, it just gave me a Canadian clothing store XD
Oh. Dressup time?

Hey, Astalon's graphics were done by the mangaka of Dragon half

Haha, yes. "Come" inside....

Of course Zone-tan knows where R34 is at, XD

@Kuraido
I was thinking the same thing. Only I was going to say Tentacle Pit rather then dungeon of toys

@Jo
Was wondering is Zone-Tan was going to make an appearance.

Out of the frying pan and into the dungeon of toys.

Astalon is a really good game at least, but yeah, I get that complaint for sure, I remember it being a bit tricky to figure out where to go at certain points in it

Every game has flaws Jo.
If you like it and know why, that's all you need to recommend it to someone.

There's someone out there who'd prefer her monster form.
I wonder how MoMoi feels about that.
