This is a nice house and the happy snail surely does not belong to this house. It has entered a restricted area but luckily there is no one else in the house at the moment. Imagine what can happen if someone comes and finds the snail in the house. So before the snail gets into further trouble it should be helped to get out of the house. There will surely be items inside the house that the snail can find and use to accomplish various tasks while trying to find the way out of the house. The poor little creature will need some help from you though.
