How to get a bottle?

You get the bottle from getting the peony flower to level 5. Then it will give out level 1 water leaves. These can be merged to get a bottle.

You get the peony seeds to make the peony flower from the level 6 vase. The vase comes from the drawer. You make the draw first of all with a single wheel caster and merging it up.

Make the draw to get the vase, to get the peony seed, to get the water leaf to make the bottle!
