He could start by being more open with his friends about his feelings. Just telling them that he sometimes feels left out might make them more aware and inclusive.
Naruto could try to reach out to the other characters. He's a very determined person, so he could make an effort to join in on their activities or conversations. For example, if they're having a training session, he could ask if he can participate.
The story of the down-and-out phoenix and chicken originated from the story of the Three Kingdoms era. It was said that Zhou Yu was jealous of Kong Ming's talent and wanted to harm him. At a banquet, Zhou Yu deliberately proposed a competition of poems, saying that if he could not match it, he would kill Kong Ming. Zhou Yu first came up with a poem, which meant that a successful cat was better than a tiger, and a down-and-out phoenix was worse than a chicken. Zhuge Liang replied, meaning that if there was wood, it would be a piece of chess. If there was no wood, it would be a piece of chess. If the wood on the edge of the chess was removed, it would be cheating. This allusion described Kong Ming's witty response, while Zhou Yu was happy because he fell into the trap. This allusion meant that in adversity, even the originally noble phoenix was inferior to an ordinary chicken.
Well, the 'left right christmas game' can become a long story in a couple of ways. First, the rules themselves could be complex and described in a long - winded way. Second, the actions in the game, like passing presents left or right, could be tied to a long - form narrative. Say, for every pass, there's a part of a Christmas story told. As the game progresses, the story unfolds bit by bit, making the whole experience a long story. It could also involve different characters in the story, and depending on where the item lands as it's passed left or right, different things happen to those characters, thus elongating the story.
The chicken's adventures can be part of the story. For instance, one day it might accidentally wander too far from the farm and get lost. It has to find its way back while facing unfamiliar sights and sounds. It could meet other wild animals and have to figure out how to avoid them. And of course, the simple joys of a chicken's life like taking a dust bath or finding a particularly juicy worm are also things that could be included in this long chicken story.
