I like the idea of the 3 eeveelutions having a story together and i think i would be cool if vaporeon had hourglass growth, flareon had futa growth and jolteon had muscle growth. Also, if you ever add pikachu, can you make them have all the types of growth?

Thanks! I think you can continuously follow the activity in discord for the development of eeveelutions. 

I'll add raichu instead of Pikachu due to my own preference. 

For all growths I would like to preserve that for legenderies or such. 

In conclusion, follow the activities and discussions in discord!
