Because there was no Brown Team, and Green and Yellow were on negative terms with each other (save for a brief alliance between Lana and Sabrina), there was no GYB alliance to be made.
It was first referred to in Tide Pull, where J.D, asks Shep if he had any close friends with other teams. He responded that Green and Brown were his closest friends, but not as an alliance. When asked about if they were going to the final three together, he mentions they have to get to the final five first.
Ironically, in Cherry Picker, Yellow was seen as the weaker team, carried by Green and Brown, and had to win the mission that day or else get sent to Temple. Despite being extremely close to winning the mission, Purple ended up winning, and sent Yellow, along with Brown, to the Temple of Fate, where Yellow was eliminated.
Afterward, both Green and Brown made it to the Endurance finale, where Brown won.
Green, Yellow, & Brown
This alliance was clearly shown in Squaring Off, where they first where on the verge of elimination, then getting control and picking off their rivals, only to get eliminated themselves after Brown chose Orange to go next. Yellow and Green were subsequentially sent up to Temple, where Green was eliminated.
After Yellow won Out on a Limb, Tom expected Yellow to pick them for their superteam because of their friendship, but Monroe didn't think so because Brown was one of the weakest teams in the jungle. They ultimately chose the stronger Gray and Purple Teams instead, and won Bamboo Jungle the next day. The Yellow Team tried to persuade the other two members to send Orange up instead with Red, to no avail. Bryanah tried to assure Tom that she stood up for him, which he shrugs off due to the results. Nevertheless, Brown came back
In Pipeline, Yellow and Brown made a secret alliance with Orange: if either one of the three teams won the next Temple Mission, . But when it was exposed, Yellow was punished for it, and was sent to Temple with Brown, where the latter team was eliminated.
After Endurance: HawaiiEdit
Because there was no Brown team after Endurance: Hawaii, there was no other Green-Yellow-Brown alliances.
- Out of the three colors involved, Yellow has yet to win Endurance. They almost won on Endurance, and was in an alliance with Blue, but didn't have an alliance with Green (who was one of the members of the Brotherhood).
- One of two multi-season alliances; the other one was PROG (or Purple-Red-Orange-Green/Gray).
- However, they are the only multi-season alliance to have the same three colors.
