Before Bam and company get to Delaware Rehoboth Lagoon April and Phil go to Delaware Rehoboth Lagoon to go find them and prepare to get on a boat to go out searching. While they are walking toward the boat you can see behind April the Hotdog raft tied up to the pier, the same hotdog raft April and Phil are going out to find. A few seconds later as they are out in the water they see in a distance that same hotdog raft and viking ship with all the boys.
Another one is where the boys tied it up to the pier got off and walked, it cuts to another angle and the raft is floating in the distance, and then cuts to another angle and the raft is magically back tied up.
