Ponderoo can be found in the Meadowbrooke Farm.
"Kangaeroo" is a combination of Kangaeru (考える, "to think, to ponder") and kangaroo.
"Ponderoo" is a combination of the word Ponder (Think carefully before making a decision) and Marsupial species Kangaroo.
It is based on a kangaroo with elements of a detective, most pointedly to Sherlock Holmes, who stereotypically wears a similar hat and collar Kangaeroo wears.
His pose is based on the Thinker.
- Ponderoo does not have his real life medal counterpart.
