20 bloonstone abilities:

Mage x/4

Dart Monkey x/4

Spike Factory x/4

Bomb Tower x/4

Ninja Monkey 4/x

Airplane 4/x

Ice Tower 4/x

Glue Tower 4/x

Sniper 4/x

Mortar 4/x

Ship 4/x

That's all I can see so far. I just got the Tack 4/x, but I think it cost me 20 bloonstones. It seems they all cost 20 at tier 4, but I don't know about Super Monkeys.

At level 19 now though and have 1202. I've used probably around 100 on revives, and one time I accidentally clicked the hot spikes 6 times trying to place my own road spikes.
