Maggie is excitedly working on the costume she'll wear to Inkli-Con (a convention for C.S. Lewis and J.R.R. Tolkien fans). Meanwhile, Sparky learns the science behind how his tail lights up, and immediately becomes disenchanted with everything in life he previously thought of as magical and wonderful. When illusionist Bryan Drake drops by for a visit, he re-inspires the crew's curiosity and sense of wonder, and helps Sparky realize that there are many marvelous mysteries and true wonders in the universe God made.
