How to Breed a Skipples
Get a Skipples Monster by Breeding:
What is the Average Breeding Time?
The average breeding time is an estimate based on the odds and how long it takes to breed each of the possible monsters from a combination. This is just a rough estimate right now. Because of some shortcuts I took, it will always underestimate the amount of time. I will be tweaking it in the future to be more exact.
This metric is the estimated time it will take breeding “misses” before the 50th percentile will get their first X. This isn’t actually an “average”, but the label needed to be short … 
It is a very valuable metric. While the times aren’t exactly right in an absolute sense (and are labelled wrong), relative to the other possibilities they should be very close to correct. So it can help you to realize that one combo would take you much longer to give X than another combo, even if it won’t tell you exactly how much time it will take.
Example of Benefits and Drawbacks
Thorder is a good example that shows the pluses and minuses of this approach. With Thorder you have a ~10% chance of getting Thorder from each of the 3 possible combinations. However, because of the breeding times of the “misses” and what those “misses” are, you would definitely not view them all as equal combinations!
Skipples + Skipples for instance has a lot of long breeding time “misses”. This is a bad thing if you want to get Thorder only. However, if you want to get a Legendary monster of any sort, then Skipples + Skipples is a more interesting choice. That is because you can get Thorder and Arch Knight from Skipples + Skipples. Meaning you have a 20% chance to get a Legendary from that combination.
With Skipples + Rabidex, you only have a 10% chance to get a Legendary, since Thorder is the only Legendary possible from that combination. However, the breeding times of the misses are shorter, and so you can expect to get Thorder much more easily with Skipples + Rabidex than you would expect to from Skipples + Skipples.
Looking at the other possible combination for Thorder, we find the “best” one in most regards. Rabidex + Rabidex gives short breeding times and 2 Legendary possibilities. While you’d expect to get Thorder a little slower than with Skipples + Rabidex, you’d expect to get a Legendary much sooner than with the other two combinations. So if you would be ok with Lord of the Atlantis or Thorder, then Rabidex + Rabidex is the way to go!
