Yip, yip hooray! Uh huh, uh huh!
Yip Yips have landed! They would like to live in houses that contain an 'Earth Book' in case they need to look something up and are happy to help with containing mess found in said houses. Whilst they are here on Earth you are welcome to use them as storage for anything that needs to be hidden.
They are approximately 45cm tall with a mouth opening of about 30cm round. They do NOT like to be washed. Spot wash with a damp cloth if you must. They do have small parts, so aren't suitable for young children.
