Hybrid Yukkuris are the result of Yukkuri breeding and bearing children that have shared traits of both parents, rather than being the exact same type as their parents.
These tend to be rare but highly sought after by Yukkuri enthusiasts and collectors.
A multitude of hybrid yukkuri have been known to exist, with the most prominent being Yukachen, a Yukkuri with Chen's ears and tails, and Yuka's hair coloring with a sunflower as an accessory.
Hybrids are surprisingly rare, given the simplicity with which they are often shown to be created. There are several methods that have been seen:
- The hybrid is a result of a mutation during reproduction.
- The hybrid is produced by a complete transfusion of paste/filling from another yukkuri. This process will usually drive it "insane", and its actions will become confused, conflicting, and as if it is trying to be controlled by two different brains. This method is not recommended, as it will not create a desired hybrid and the fused yukkuri will end up dying.
- Artificial hybridization can be performed by slicing in perfect halves two Paste Cores coming from two individuals of different types, and then reattaching the left half of one with the right half of the other and vice-versa with the help of a mix of 97% orange juice and 3% flour. The hybrid Paste Cores are then placed again into each yukkuri's body which reactivates life. Although, if not dead, the yukkuris will be most likely insane/catatonic/both. Induced fertilization is made, with the resulting offspring taking half of the traits from one type and half of the other due to copying the "new" Paste Core. The koyyukuris may or may not be born with "mental" disabilities. While this method is used by the Factory to produce hybrids on a massive scale, many owners and yukkuri collectors simply disregard this method, finding these hybrids inferior to "real" ones as well as the many issues that said yukkuri will suffer throughout its life.
- It is also known that when a Yukkuri was ready to reproduce, some of its offspring will look like the nearby Yukkuri which was near its parent Yukkuri.
