Warning! Star Wars: The Last Jedi spoilers!

When it comes to Star Wars cameos, there is do or do not. There is no try. And The Last Jedi certainly did.

In the film after Rey (Daisy Ridley) leaves Ahch-To to make contact with Kylo Ren (Adam Driver) a frustrated Luke (Mark Hamill) decides its time to destroy the ancient Jedi texts and the tree they are kept in. In that moment, the audience is treated to the return of everyones favorite little Kermit the Frog/Miss Piggy hybrid, Yoda .

But its not that weird, acrobatic CG Yoda from the prequels. Its puppet Yoda, with a Force-ghost glow.

Force-ghost Yoda returns to talk some sense into Luke, and it works. Luke seems to have a change of heart over Rey and the Jedi. And, just because hes got style, Yoda uses a lightning bolt to destroy the ancient tree and (supposedly) the Jedi texts with it anyway. His explanation: Theres nothing in there that Rey doesnt already possess.

On the Yoda scene, director Rian Johnson said, That was something that very early in the process I realized would make sense, especially when Lukes arc started to define itself. He added: I thought, well, who can actually kick Lukes butt a little and speak truth to this guy? And the obvious answer was Yoda.

The Force is with that cameo, but theres also a secret for watchful viewers.

Remember that while he was destroying the tree, Yoda claimed there was nothing in there that Rey didnt already have. Later in the movie, the Jedi texts briefly appear on the Millennium Falcon, a shot Johnson confirmed to HuffPost. Apparently, Yoda said all that because Rey had already taken the books.

Youve got sharp eyes, Johnson said when we asked him about the books showing up later.

Thankfully, other behind-the-scenes Star Wars crew members shared their secrets about Reys discovery of the Jedi texts (and Yodas cameo):

That Yoda was close to the original.
