I've located what appears to be the gas stove in Sakura Town, the thing under the pot in front of the chef. But the game dosen't let me roll it up. Help!

Either it's not a rollable object at that point in the game, or you're not big enough..

Well, I found one place in Sakura Town to get the gas stove, I don't know if it's the only place.

The gas stove is just a little metal burner. It's on top of the stove-like thing on top the hill past the 75cm barrier. It is very small. To get on top the stove thing first grow to at least 1m50cm, or it would probably be easier if you become big enough to roll up the person blocking your way first.

Oh, I was thinking it was inside the resturant in Sakura Town. I had the right place.
