I ask all my fellow BIONICLE fans to start waves on LEGO's social media pages for them to do something to commemorate the occasion, like rerelease some of their most beloved sets like they did for LEGO Star Wars' 20th Anniversary. Remind them that the original BIONICLE helped save them from bankruptcy and if they don't do anything it would be a huge disservice to the line and the fans that enjoyed BIONICLE all those years ago.
I don't know much about SCP stuff but I feel like Bionicle has enough cosmic and body horror themes that it would be thematically appropriate to make a series of like Onu-Metru archive journal entries about the Rahi they were studying. If anyone who knows more about the SCP Foundation wants to do something with that idea please go ahead.
