While a great majority of the series' episodes were animated by Korean animation studios, "Adventure Time" occasionally featured guest animators and directors. For instance, the second-season episode "Guardians of Sunshine" was partly rendered in 3-D to emulate the style of a video game. The fifth-season episode "A Glitch is a Glitch" was written and directed by Irish filmmaker and writer David OReilly, and features his distinctive 3-D animation. Animator James Baxter animated select scenes and characters in both the fifth-season episode "James Baxter the Horse" as well as the eighth-season episode "Horse &amp; Ball". The sixth-season episode "Food Chain" was written, storyboarded, and directed by Japanese anime director Masaaki Yuasa, and was animated entirely by Yuasa's own studio Science SARU. Another sixth-season episode, "Water Park Prank", features Flash animation by David Ferguson. A stop-motion episode titled "Bad Jubies", directed by Kirsten Lepore, aired near the middle of the show's seventh season. Finally, Alex and Lindsay Small-Butera, noted for their web series "Baman Piderman", contributed animation to the eighth-season episode "Beyond the Grotto" and the ninth-season episode "Ketchup".
