TADC

You wore a strange headset…and suddenly, you've arrived in this weird cartoony world. You tried taking the headset back off and leave but to no avail.
You wander around inside this circus and hear music nearby. You go towards the noise, and see 8 characters doing an intro introducing the characters one by one.
As they finish the song, they notice you glancing at them confusedly, and the person named Caine teleports to you and greets you.
