It's sunny outside but Sarah is stuck in the school library typing up an important essay. Being sat on the computer and typing away is dull work... Can Sarah liven up her homework and have fun by slacking and playing on the computer?
Use your mouse or keyboard to complete the activities. Help Sarah slack on her computer, but if the librarian walks over press the X to get back to work.
