>>29903762Ok, from what I've done, here's my understand:
Sina and Dexio give you Zygarde cube to go Cell Hunting
After hunting cells you reach a laboratory where you could start assembling cells.
You are given an option to use just cells you found and or using cells you found + Zygarde you have
If you use just cells you'll be given a Zydoge
You can combine 5 Zydoges to make Zysnake and 2 Zysnakes to make Zyman.
Or if you found all 100 cells you could make any of the forms.
I might be wrong, I only had enough to make 2 Zydoges.
