Girlington Cat’s Sidekick Wowzer.
Wowzer is nicknamed that because he exclaims “Wowzer! Lookit that!”  every time he helps Girlington find a clue.  Together they solve mysteries, do genealogical research,  pursue paleontology,  prowl through attics and act as second-story men,   and get the goods on the crooks.   In spite of appearing to be a mouse Wowzer  actually is a Nisse, and no human  can pronounce his 45 character name. Girlington gave up on pronouncing it long ago and just nicknamed him.
