Hey Pandas, What Is Your Most Creepy Experience With A Toy?

I had one of those handheld Tetris games at one point. Loved that thing. However, one night I heard this really eerie clicking in my room. I got up, searched my room in the dark ( not the best decision, but it was like 1:00 in the morning) and finally just woke up my mom to help me look. We looked and looked and looked. We finally found that the game has accidentally been left on and was running out of battery. We turned it off, but... It still kept going. My mom took out the batteries as quickly as possible and said, "If that thing starts up again, I'm throwing it out the window." Turns out that batteries had just been corroded, but it was still freaky.
