Lizards in the kitchen
Another place to hide lizards (or anything you think would scare your friends) is in furniture or electrical appliances. A lizard or two can hide in some cabinets, in the fridge, and inside the microwave. Take a look at this little guy.
If you want to put lizards inside microwaves, use a rubber one. Remember, people could turn the microwave on without realizing there is a living creature inside. Imagine opening the microwave to make popcorn: SURPRISE!
