Janitree

Janitree is a plant that cleans the puddles on the tile that is planted on. It can be planted on any puddle, even the X-shaped puddle!

Strategy
It is best to plant this on the X-shaped puddle to unlock the tile. Remember that it can be planted on any puddle, so it can also be planted on the sun-producing only, peashooting plants only, and instant uses/ground-only only puddles! Useful if you don't have one of those plants.

Trivia

 * Janitree is a portmanteau of tree and janitor, a person that cleans stuff.
 * According to Janitree's almanac entry, he is paid 25$ each month.
 * His salary is the same as his sun cost, it was possibly based on it.
