Tobi was friends with Kisame only one a year, Christmas time. They had fun together decorating the base, tree, and the member's rooms. Of course Kisame always left Tobi to decorate Zetsu's room by himself.
"It's just that you know Zetsu better than me, kid." That's what Kisame said when asked once. So every year when Kisame was decorating the roof, Tobi did Zetsu's room.
"Tobi, why are you in my room? Aren't you usually with Kisame this time of the year?" Tobi turned from the lights he was putting up near Zetsu's plants.
"Um…I'm decorating your room because Kisame told me to do it while he was of the roof. I'm afraid of heights a bit, Zetsu-san," Tobi rubbed the back of his neck sheepishly. "I can come back later if you want."
"No, it's fine. Just be careful with my plants." Zetsu walked to his desk and sat down.
"H-hai, Zetsu-san." Tobi turned back to what he was doing and finished handing up the green lights that gave the plants a more green tone than usual.
"Um, Zetsu-san, where do you think I should hand the mistletoe?" Zetsu turned around to look at Tobi who was looking around helplessly to find a place for the plant.
"Mistletoe? Isn't that supposed to be poisonous?" Tobi dropped the plant and scooted away from it.
"That's not nice to tell him. Well, it is poisonous. Only if you eat it, you know that. Are you saying I should be like you and be all nice? No, I'm not saying that but still there's no reason to be mean to Tobi. Hn." Tobi reached to the plant and picked it up, inspecting it. He couldn't see that well so he took off his mask to get a better look. It didn't look poisonous.
"Hey, Zetsu-san, do you know about the legend of the mistletoe?" Tobi walked to Zetsu and stopped in front of the cannibal. Zetsu nodded and Tobi lifted the mistletoe. Reaching as high as Tobi could, he couldn't get it over Zetsu's head. Tobi jumped and still couldn't reach the top of Zetsu's plant head thing. Zetsu sighed and plucked the mistletoe from Tobi's hand.
"Consider this your Christmas gift, after all Tobi is a good boy." Zetsu leaned down a bit and captured Tobi's exposed lips with his own. Standing up straight again he turned to leave when Tobi called out.
"Merry Christmas, Zetsu-san!"
