To Touch a Hummingbird - S2-E10
Other mistake: Chris gets on the zip line and hooks up. Martin just stands behind him, not hooked up to the zip line. Chris zooms off down the line chasing the hummingbird. A few seconds later, Martin is suddenly on the zip line also and right behind Chris.
Other mistake: When Aviva makes Turkey Power Discs, the Creature Power Suit buttons are looking angular and plain instead of round and convex.
Groundhog Wakeup Call - S2-E25
Continuity mistake: A couple of seconds after Aviva (in Groundhog Power) has made a hole into the Tortuga's floor, in one shot the main screen is suddenly cyan instead of blue.
Suggested correction: The cyan main screen is actually not the case in "Groundhog Wakeup Call", but in another Wild Kratts episode, the error is shown.
