Trivia

• Featured Pokemon: Nuzleaf
• Team Magma uses the object much later to get the Groudon.
• This episode's title is a reference to the term "seal of approval".
• After this episode, Pokémon underwent a nearly three-month hiatus on Kids' WB!, and did not return with new episodes until September, despite the new season not beginning until What You Seed is What You Get.

Errors

• The hint given in the Who's That Pokémon? eyecatch, "This Pokémon lives in in the forest and enjoys startling people!", has an extra in.
• In the Hungarian dub a Team Magma Member asks his Mightyena to use "Shadow Bell" instead of "Shadow Ball".
• While Ash, Max, and Marius are eating snow cones Ash and Marius' snow cones trade colors. Ash's snow cone became yellow, and Marius' became green. This was corrected the next time the cones were shown.
