Questions about Wren and Bixby's Undersea Adventure

What age is Wren and Bixby's Undersea Adventure for?

Kids ages 6 to 10. The scenes are detailed and the hiding spots are tricky, so older kids get a real challenge.

How many pages are in Wren and Bixby's Undersea Adventure?

50 original coloring pages. Each picture is printed on its own sheet, one side only.

What is hidden on every page?

Message in a bottle. One hides in every scene, and kids search for it once they finish coloring.

Will markers bleed through?

Bleed-through won't ruin another picture, because the back of every page is blank. Slip a sheet of scrap paper behind the page if you're using heavy markers on a nice table.

Where can I buy it?

Wren and Bixby's Undersea Adventure is sold as a paperback on Amazon. Use the Buy on Amazon button at the top of this page.
