This mistake is moderately bad. Puppycorn's gold medal that he received after Hawkodile and Dr. Fox wakes up with a mood that they could not sleep. There are two errors on the medal. One after FeeBee explains Puppycorn what happened. That ain't right, then it appeared back, Two, when he entered his room, his medal is gone that comes back after crying.
Not only the medal, the crown! The crown disappears during UniKitty and Puppycorn crying then reappears.
You see the "Gold Medal" keep disappearing during the episode? That is a really strange and bad error. The medal "PP" disappeared twice. One, when Puppycorn was talking to FeeBee what happened halfway in the episode, you see it was gone, then it reappeared after that. Two, that one was worse, when Puppycorn entered his room, his medal disappeared again, then after they got done crying, his medal APPEARS.
Back to the medal part, it disappears when they head out to tell the citizens. I think he took it off.
