I have some Slime and Pie's, and I would like to know what ideas you have for me, to make a pre-recorded video

I hope I can get something soon

Will you have someone available to apply the pies and slime or will you need to do everything yourself?

Both someone can help me or I can help myself

You can dip your finger into a pie, pretending to eat.

Your helper says, "Those were for the party.

"But--" you start to protest.

He dumps a bucket of slime over you.

"But--"

Another bucket.

"But--"

The third bucket.

You throw a pie at him (it can connect, or he's off camera. There's then a pie fight. You're hit in the face and temporarily blinded, As soon as you clear your eyes, he pies you again.

What did you use for the gunge? It looks lovely and thick, and I just wanna dive in!

If you're working with someone, you could push the boat out a little and have them handcuff/tie your hands behind your back. [A 'hardmode' game can also be played with the addition of ankle restraints too]
The password to release your hands is hidden in one of the pies. However some of the pies have the 'wrong' password**, which will release the gunge instead.

**this game may or may not be rigged, with the right password being in the final pie or hidden in the gunge bucket
