Probably the quickest way to wrap it up is to make it awkward to continue. It’s not like you can’t handle a little embarrassment. You’ve already stopped your performance, so you just need to get down your makeshift structure.
And it’s easy enough to “accidentally” knock it over just before you reach the ground. You miscalculate a bit and stumble more than you meant to, landing on the ground rather painfully.
“You okay there?” the grebling asks. “This seems like the sort of thing you ought to do with soft cushions nearby, and trained professionals around to catch you. Not in an open field with nobody nearby except a single grebling. I wouldn’t be able to carry your weight for very long.”
“I’m fine,” you say with a wince as you get up. “This is mostly a blow to my pride.”
You grab a small barrel and walk off without another word, leaving the grebling confused. Then you put the barrel back where you found it and head over to the sundial, where Len is waiting.
Wordlessly, you start turning it based on the combination you saw, using the standard order of elements. Water, wind, light, fire, earth, sound. You hear something click on the last turn.
What you do not hear is the sound of a secret door opening. Either it’s somewhere else entirely, which seems like an odd way of doing things, or there’s another step you have to figure out.
Tap your ear, then the sundial with your palm in a searching motion. This usually means “listen for the cue” in a stage play. Hopefully he rests his ear on the sundial or something to find clues
“Again, from the top” circle the sun dial in the air with your finger then tap it. Let him know you’ll Repeat the sequence
Mimic rotating a small cube in your hands, then shrug, this lets Len know you did the steps but the puzzle isn’t solved yet
No need to say anything, just Look around the sun dial, start brushing the dirt around the sun dial for clues. Len will pick up on it
