In Venomous Pond, there is a Dark Temple Key that you 'need' Grapple Beam to get... Bzzt. Wrong!
Near the Save Station there are 3 Ingsphere Caches. You will need to practice L-Lock Jumping before doin' this simple trick succesfully.
After looking as far down as you can, hop onto the Biggest cache, and just jump to the key.
In Path of Roots there is a slant that you can underwater IBJ up. After a certain point you can use 4 more bombs. its on the Torvus Lagoon side of the missle expansion.
