Keep one player at the rock-hidden case, send a listener to the distant audio station, and use the active song cue to choose the remote control.
Find the reward case concealed among large rocks near the speaker area and leave one player beside it. A second player uses the green listening chair and follows the audible route toward the blue, green, then light-blue radio-station area. At the remote station, compare the current song or sound cue by rhythm and repetition, locate the tucked microphone/button control, and communicate with the case player. Trigger the matching control while the case player waits ready to collect the reward. The cue is current-world audio, not a permanent song code.
One end is a case hidden among large rocks near the speaker area. The information end uses the green chair and a distant radio-station route; the qualified source follows blue and green landmarks to the light-blue station and its tucked control.
Search the large rocks near the speaker area, identify the concealed reward case, and leave one collector there.
The collector can touch the case as soon as it opens.
Seat the runner, listen to the distant cue, and confirm which direction or station family becomes audible.
The runner has one current sound to follow.
Travel in daylight if possible and verify each coloured station before continuing toward the light-blue radio area.
The runner reaches the station containing the remote control.
Replay or compare the active sound, count beats and pauses, and reject candidates with a different repeat pattern.
The chosen control matches more than a vague melody.
Inspect low corners and the station edge for the small remote interaction shown by the source.
The interaction prompt appears on the concealed control.
Confirm the case player is ready, activate the matching remote, and keep communication open until the reward is collected.
The distant case opens and the Red Blob is secured.
Use one player for each information or action side. The collector never leaves the case; the listener runs the radio route.
Keep the two core roles unchanged. Extra players should spot, carry, or record the current sequence without creating a second caller.
