|The Rhyming Rocks of Ecum Secum|
The Rhyming Rocks of Ecum Secum are rocks that live in a cave in the Ecum Secum Circle.
The rock brothers are three rocks who frightened Pugwash when she dove in the Ecum Secum Circle (a place where ships get lost forever). They always speak in rhyme; except the third rock who adds something.
- Ecum Secum is also the name of the rural community located in Nova Scotia and comes from the Mi'kmaq term for "Red House".
- The Rhyming Rocks of Ecum Secum were the last characters introduced in the series.
