A old April Fools idea I had was the idea of the Neighbor being able to get some of the Explorer's Emotes, complete with voice lines. Just imagine how funny it'd be to see Mr. Peterson saying 'Hello!', 'Key Found' or like running around the house yelling 'Help!' or 'It's Dangerous Here!' when Mayak is happening.
I imagine it'd be a sorta thing where it'd be limited time to buy for April Fools (Appearing in Featured Items or Daily Items instead of simply in Emotes.)
