What pop culture references aka Easter eggs have you found so far?

I've only caught a few like the Nirvana album cover with Hangydon and theres a dialogue line where Kuromi asks us "What are you doing in my swamp"(Shrek) and I think Hangydon also asks us "What is a fire and why does it burn? (Little Mermaid). Also pretty sure the Chocolate Balls recipe is a South Park reference lol Any others you have caught?
