Trivia

 * Sandy Tentacles appears on the menu screen, suggesting he is the final boss and possibly the leader of the lumps
 * There was a mistake with his name due to his character name being called Sandy Squid in the Help option but his level name is called Sandy Tentacles. However, the Sandy Squid name is used for Evil Sandy's level.
