What tricks did tom and huck play on Jim?

After being separated by a fog, Huck wakes up and sees Jim sleeping on the raft. He ties the canoe back to the raft and lays at Jim's feet, pretending to be sleeping. When Jim wakes, Huck pretends that Jim dreamt the whole fog incident. When Jim finds out Huck is pranking him, he is offended. He says that after all the work of trying to find Huck and calling for him, he didn't care about himself or the raft, only about Huck's safety. When he woke up and saw Huck alive, he was so happy he could have kissed Huck's feet. All that time all Huck cared about was making Jim look like a fool. After Jim says this, Huck sees how mean his prank was and feels so bad he could have "kissed his foot to get him to take it back." He apologizes to Jim.
