The Legathon

The Legathon is an event that happened in the fanon timeline of the legs. Fred died of an accidental overdose on painkillers and many united fans and executives of legbreak records joined in, along with Spongebob in the crowd, who went on to be a member of multiple music outfits.

The Days Leading Up To The Event
Fred Rechid had been admitted into hospital after a painful sequence of events, resulting in a seizure in his small Spongeopolis apartment. After taking one extra pill because he was having a migrane, the intensity of the pill caused him to fall unconscious  off of his balcony and start shaking uncontrollably on the ground.

Fred's heart is being monitored for any worrying conditions. Frank is barely conscious. Frank wakes up only to flatline three minutes later. He's dead.

Frank was pronounced dead on the 9th of January, 1989, on the supposed release of his twelfth studio album, which was delayed until a year later.

The Actual Event
Frank's death is originally ruled a suicide, so his fans decide to run from Bikini Bottom to Rock bottom in his honor, from Conch Street down to the 90 degree hill.

The run starts and only half the people finish, the other half finding warmth in Rock Bottom.

The news comes out that Frank's death was accidental and they decide to burn a bottle of the pills he was taking.
