Disguised as a store clerk: surprise prank

A prankster disguised as a store clerk.
As a birthday surprise, a cake was brought out.
He was hit in the face with the cake by the “clerk” and had his face roughly wiped as part of the prank, and he didn’t realize at all that the clerk was actually a disguised prankster.
In the end, he noticed the disguise and was even more shocked.
Send a celebratory LINE message to everyone at once
Isn’t almost everyone keeping in touch with friends on LINE? Here’s a surprise idea: send a flood of celebratory LINE messages all at once.
The plan is to decide on a time in advance and have everyone send their congratulatory messages simultaneously.
If you send from individual chats, the screens will fill up with celebration messages, boosting the sense of happiness.
Try thinking up warm messages to send.
As a variation, you can also send stickers or gifts.
Be celebrated by strangers

When it comes to birthday surprises, many people probably think of throwing a surprise party.
The usual setup is to call the birthday person out under some pretext, and at the destination there’s a venue ready to celebrate—plus their friends.
But how about this twist: arrange for a complete stranger to congratulate them instead? Since it’s a stranger, choose someone who seems as un-suspicious and refreshing as possible to do the celebrating! And be sure to capture the whole scene with a hidden camera!
Homemade bento as a present
How about a heartwarming surprise with a homemade bento? The contents can be anything, but it’s nice to tie them to a birthday or to the person themselves.
For example, you could recreate a birthday cake in the style of a character bento, or pack it full of their favorite foods.
This is a surprise you can pull off either by yourself or with a group of friends.
Beforehand, don’t forget to tell them, “Don’t bring a lunch tomorrow!” Alternatively, you could focus mainly on desserts.
“Congratulations!” in a reverse playback telephone game

Do you know the reverse-playback telephone game? The reverse-playback telephone game is a version of the telephone game played using a recording app that has a reverse playback feature.
Players can only listen to what’s being said in reverse, so it’s more challenging than usual.
It’s also great for birthday surprises.
Make the birthday person go last and pass along a keyword like “Happy Birthday.” When they figure it out, they’ll be both surprised and moved.
