 Layout and Concept
The Layout of the Bi-Annual jellyfish Convention is of a fairly organized and structured convention. The exterior of the stadium is very good and it has been set up well. There is a huge sign in a red text displaying: 'WELCOME JELLYFISHERS'. There are many entrances to the inside and there are many boats surrounding the convention. Around the area of the stadium are Jellyfish shaped balloons.
Inside the stadium it is neat and of a great standard. There are many tables with different things on them such as jellyfish in jars and pictures of them. The theme of the layout is Jellyfish, as there are banners, balloons and signs all to do with Jellyfish. There is also a Jellyfish Harpoon from Jellyfish: The Movie. There are also stages where people talk to the members of the crowd.Patrick needs to be followed around by a policeman because he cannot stop touching everything he looks at. SpongeBob buys his purple Jellyfish hat at the convention, too.
now, it is possible that kevin runs the convention.
