The training of Miles Morales continues in the newest clip for Spider-Man: Into the Spider-Verse. If you thought being Spider-Man was easy, think again.

The clip begins with Miles and Peter Parker breaking into a laboratory, where Miles soon finds that even performing simple maneuvers can be a challenge. Take hanging from the ceiling, for example. Letting go is a lot easier than it sounds.

Eventually, Miles is able to relax and let go, causing him to come crashing to the floor. It’s then that he realizes he has a particularly useful power.

“Can Spider-Man turn invisible?” Miles can!

Miles’ invisibility is then used to great comedic effect just as he and Peter are about to be caught. The chemistry between Miles and Peter unfolds beautifully, with plenty of humor and charm.

Spider-Man: Into the Spider-Verse hits theaters on December 14.
