Sweetling reproduction begins when two Sweetlings copulate. The product that exits their genitals, regardless of actual composition, has the necessary bits of ‘genetic code’ in order to set production into motion (This code can enter in anywhere in the body, it will always be brought down to the stomach area).
This means, however, that only Sweetlings can only impregnate other Sweetlings, and can only be impregnated by fellow Sweetlings.
Due to the flexible nature of the species, either sexual organ can be created and are functional, regardless of base gender.
A short time after copulation, a clutch of eggs made of a fusion of materials of the two Sweetlings will start forming within the body. The eggs take roughly two days to incubate before being ready, at which point they can either be removed from the body or kept inside.
Inside each incubated egg is a Necco. Each of these Necco has the potential to create a Sweetling, but a host must be found before the process can begin.
The eggs themselves have a shelf-life of sorts, only able to survive a couple of days outside the body and about two weeks inside. If an egg is not used before it’s expiration, the Necco within the egg will break apart into sugar, and the eggs will simply absorb into the rest of the form.
There are two factors necessary in order to create a Sweetling. They are:
A: An incubated egg from a Sweetling
B: A non-Sweetling recipient
For the change to begin, the recipient must make contact with the newly formed Necco. This can occur in many ways: the recipient consuming the egg containing the Necco, pressing the Necco against them, etc.
Once the Necco and recipient have touched the imprinting process begins. During this time it is possible the recipient may not even know what is going on, as the Necco copies and transcribes all the mental history, personality, likes, dislikes, and overall ‘being’ of the recipient into itself. Some have reported hearing the “new them” talk during this phase, but the evidence on this is inconclusive at best.
After the imprinting process has finished, the Necco sets of a chain of events as the proper transformation begins. The Necco sends out a signal for materials chosen for the form (as dictated by the imprinting process), the materials pulling towards them in a rather aggressive fashion. Typically another Sweetling will be around to help with this process, however in the event that they are not, the core will naturally increase the desire to consume the chosen material, drawing the recipient closer to their change. The materials will travel towards the individual's body, filling out the new shape and covering their body as the original form breaks down underneath. A momentary blackout typically occurs as consciousness transfers to the Necco, but it rarely lasts more than a couple of seconds. The chosen sweets continue to fill the body until the Sweetling is complete in their base form.
If the Necco is not given access to the base material of its new body for a full three days after imprinting, the process will be canceled, and conversion into a Sweetling will not occur.
