Aunt Lucy knows about a special talisman that may cure the illness and joins Franklin on a quest to find it, with his friends Bear, Beaver and Snail.

They are also accompanied by Aunt Lucy's goddaughter, Samantha (Sam), whose personality clashes with Franklin's.

The film, released to direct-to-video in the United States by HBO, has had occasional TV airings on the Nick Jr. Channel.

The Turtle family visits Franklin's grandmother with Aunt Lucy and her goddaughter, Samantha (Sam).

Granny flashes back to when she was a child in Turtle Lake and spent mornings fishing with her father and afternoons picking berries with her mother.

She found a secret hiding place and buried her valuables inside a painted tin box, but never got the chance to open it again.

Thinking that the box may be their only hope, Franklin, Sam, Lucy, Beaver, Bear, and Snail head to Granny's old, ruined home.

Franklin and the Turtle Lake Treasure is available in French and English versions, which have different case covers.

Anna Hart of the Empire called it an "Unecessary spin-off of a fairly lame children's animation.
