How do I hide a cell phone in the wall?
 

My sister wants to sell her house and purchase an old place with six bedrooms (for her three kids). I think it needs Scooby Doo ghost noises.

I am thinking:
1. Visit
2. Pull an outlet out of the wall
3. Set the ring tone on a cheap prepaid phone to my preferred Scooby Doo noise.
4. Wire the charger into the outlet, hide the phone in the wall, and put the outlet back.
5. Apologize profusely when I burn down the house.

Obviously it would be easier to convince a real ghost to live there, but I am not sure those are available at Wal-Mart.

I remember having seen safes disguised as electrical outlets. Search for "tomada cofre" for inspiration.

Go with the Annoy-a-tron prankster pack and toss the Eviltron in a duct somewhere.

Six scary sound choices (5 sounds plus a random option):
Something unsettling creaking
Unidentifiable scratching sounds
Gasping last breath
Sinister child laughing
Eerie whispering of 'hey, can you hear me?'
Random/Alternating Mode


It says the non replaceable battery is good for a month.

Non-replaceable? Challenge accepted! :)

I have a good suggestion, but given the scenario, I'll withhold it.
