Yoylecake

Yoylecake is a fictional food that appeared in BFDI and BFDIA. It is made from exotic Yoyleberries, which originated from Yoyleland. Any object who eats it becomes a grey, metal version of themselves made from Yoyle Metal.

Appearance
It is colored royal purple and neon green, lined with yellow icing and decorated with orange icing drops.

Coverage
The first appearance of Yoylecake was in Episode 21, though it has been mentioned several times before that, mainly by Bubble, due to the fact that "Yoylecake" is her catchphrase. For example, when Bubble is told that she has immunity, she mentions it in the previous episode.

Later in the same episode, during the long jump contest, Bubble, having eaten the Yoylecake, turns metal midair. Leafy then mentions the side effect of turning metal by eating Yoylecake.

In Episode 22, the cake used for Cake at Stake is the Yoylecake. At the end of the episode, everyone turns metal, because they received a slice of the cake and ate it.

Trivia

 * Yoylecake had won the Battle of the Fantasy Foods 2016.
 * In BFDI 22, all contestants turn metal at the end of the episode. This shouldn't happen, as they have died at least once in the episode before turning metal and shouldn't have retained the side effect.
 * Yoylecake is Bubble's catchphrase.
 * Yoylecake was once a recommended character.
 * The creators of Battle for Dream Island (BFDI), also created a channel named "Yoylecake".
 * Yoylecake has not been mentioned at all yet in BFB, but this could change as BFB continues.
