Clearly, popcorn (or more specifcially, popcorn kernals) evolve when you put them inside the microwave and bring them to up to temperature to for several minutes. If you aren't careful, your popcorn will devolve into burnt pieces that are weaker than Magikarp.
I hope that helped!
It is suppose to evolve at the Level of 20,but if you want it to evolve later it can evolve anything after it is at Level 20.
It will evolve by level. Teddiursa will evolve into a Ursaring at level 30.
They evolve at level 36
It will evolve at level 36.
They evolve on level 40
it evolve on level on 64
Usually you put popcorn into the microwave for about 2:30 , but it depends on the popcorn, the microwave, and the heat level.
if you dont let it evolve at the required level of level 20. itll try to evolve at every level following.
To evolve a Sandshrew level it up to Level 22 and it will evolve into Sandslash.
Pikachu do not evolve by level. They evolve when a thunderstone is used on them.
Kricketune does not evolve, but a Kricketot will evolve into Kricketune at level 13.
Level 40.It will evolve at level 40.
