After you finish my loop the last part is along a road which has some of the Tytherington Triangle on it.
Most of these caches have small swap items.
This cache is named after one of the many characters in the films
Voiced by: Michael Keaton
Ken is a smooth-talking doll who falls in love with Barbie. He first appears wearing light blue pleated and cuffed shorts, and a tucked-in leopard-print shirt with short sleeves. His accessories include matching ascot, sensible loafers and a fashion-forward gold belt. He lives in Ken's Dreamhouse, a big yellow doll house with three stories, a large wardrobe room, and an elevator. Barbie originally breaks up with Ken when she finds him, Lotso, and a reset Buzz Lightyear locking up her friends. Piqued, Ken orders her locked up as well.
However, as part of a plan to escape, she pretends to forgive Ken, gaining access to his dream house. Barbie then ties Ken hostage to try to get him to reveal how to reset Buzz back to normal. As a provocation, she rips his clothing apart. Ken reveals the truth after she begins to sabotage his Nehru jacket. He is not seen again until Lotso has the toys cornered at the dumpster. Ken comes to Barbie's help by trying to stop Lotso, having realized Barbie through her understanding of civics. Lotso tells Ken "there are 100,000,000 others just like her", but Ken insists that for him, there is no one else like her, and wins back her affections.
If you have not seen the films they are well worth watching.
