Oh yeah, the yoyleberry has some extreme side-effects, sorry.

Yoyle Metal is a material that is produced when Yoyleberries or Yoylecake are consumed by a person or object. It is unknown how it is formed. It makes said person made out of Yoyle Metal.


In "Hurtful!", the metal was extracted from the contestants to fix the Tiny Loser Chamber via the Incinerator.

Leafy was made of Yoyle Metal in most of BFDIA, due to living in Yoyleland.


  • It is unknown if Yoyle Metal can be made in any other way. or what materials it is made of.
  • It is unfreezable, although normal metal is.
    • However, this has only been tested using Freeze Juice, so it is possible that it could still be frozen through other means.
  • When turned into Yoyle Metal, Bubble is called Metal Ball (as a recommended Character, and by Firey Speaker Box).
  • The Recovery Centers do not keep the Yoyle Metal on someone if they die, making it the only way to get rid of the effect.
    • However, in the BFDIA 6 deleted scenes, Fries says he has an Anti-Yoyler, which reverses the effect. However, it is unknown if this device exists in canon.
    • Yoyle Metal also affects hosts.
  • It is extremely heavy, as seen in "The Glistening" while Bubble is trying to jump.
  • It can affect any object, even if they are already metal.
  • Yoyle Metal appears to be the same color on the fixed TLC but different when in object form.
  • Yoyle Metal has affected eleven contestants and one host so far.
