Join the fun as Max and Ruby give grandma a party.

Max and Ruby are having a birthday party for Grandma. Ruby has invited seven stuffed-toy guests she's sure Grandma will like. Max wants to invite his Jellyball  Shooter Spider, his Ear-Splitter Space Cadet, and his Can't Sit Up Slug, but Ruby says no. Yet each time Ruby counts the number of guest at the table, another one has mysteriously appeared. Is Ruby having a bad counting day? Or is somone making changes to the guest list?
