Pekora came to assess Aqua's house only to get prank by her 

I love how she would also normally be the first to think about this

Yeah, as soon as she sees the water at the bottom, she gets off the ladder again. Pekora's minecraft skills are well honed.

why the "Red Flower?" Where did that come from?

@@runringlee8100 I think is just a short of "aqua harassment" because she push her down, just like pawahara/sekuhara

@@karlheinzschneider6688 It's actually a reference to that "Weird House" video that Pekora reacted to recently where a character is called Kugihara and he explains what's weird about a certain house.

nene and aqua is role role playing

Adding to that if you don't know Aqua is a hardcore fan of SAO and i think Nene met Aqua once at the beginning and asked to be partners since the others already formed groups. Nene then said she can be her Asuna with also mentioning her hair being quite similar to her.
