The Royal Jelly Shop sells Royal Jelly. It is located on a hill between the Rose Field and the Pine Tree Forest, just next to the Blue Cannon.
The first Royal Jelly you buy costs 100,000 honey. Each subsequent Royal Jelly will cost an additional 2,500 honey, up to a maximum of 1,000,000 honey per Royal Jelly.
The formula for the price of one Royal Jelly is
$ P(n) = \begin{cases}100{,}000+2{,}500n & 0 \leq n < 360\\1{,}000{,}000 & n \geq 360\end{cases} $
where
$ n $ is the amount of Royal Jelly already purchased.
Royal Jelly can be purchased in groups of 1, 10, 100, or 1000.
