Enriched bird poo
From Toadwater Guide
"Enriched Bird Poo" or EBP originates on statues. If there are droppings on a statue, walk on the statue to wipe off the accumulated EBP. There is also a chance to receive tree seeds while wiping off EBP. EBP has a multitude of uses.
· It is superior to any other poo in the fact that a square fertilized to 100% with EBP will grow crops or trees twice as quickly as normal.
· As opposed to fertilizing ground to 100% with any other poo which makes planted trees have double the chances of maturing, using EBP in the same way will triple the chances of maturing.
· Certain higher level crops require the use of EBP for planting.
EBP is spread in the same way as worms or other poo. Select the EBP and then click a grassy area nearby. You can also fertilize an area that is partially fertilized with EBP already.
