The preface reads:
A chill in the air… A shiver down your spine… A gnawing sense of dread… The Haunt is in a playful mood! His favourite game to inflict upon unsuspecting victims? Trick or treat! You’ll have to guide your characters through The Haunt’s mischievous tricks and steady your nerves to avoid being overcome by fear. Take solace in the fact that there’s no trick without treat, but don’t be fooled – there’s only so long before he gets tired of just toying with you…
Additionally, this challenge is available on the official Tabletop Simulator, just load up The Binding of Isaac: Four Souls Requiem+ and select Challenges from the starting game options.
