Forgotten Garden is an unused special mission in Bloons Monkey City Mobile and possibly Bloons Monkey City. It is a 10-round Yellow Sneaky Camo tile with an internal difficulty of 6, meaning it will start out as a Very Hard difficulty and appear very close to the center of the city. Round 10 will always spawn 5 Leads. It will reward an unused undroppable Special Item, the Heart Fruit that gives an extra 10 starting lives. Another trick is that for part of the map, bloons can be seen but not attacked.
