You read an article that penguins give rocks to their significant other or best friend or loved one. And being the curious thing you are, you decided to give rocks to your friends, Naruto, Sasuke, Sakura, Shikamaru, Choji, Ino, Neji, Lee, Tenten, Kiba, Shino, Hinata, Gaara, Kankuro, and Temari.

You walked to Naruto's house because they were all hanging out there and kicked the door open but not breaking it (obviously), gaining the attention of everyone.
