- 1 Rainbow Gem will be received upon first clear of each cavern
- Former Friday Limited Event(s) (Note: Since early November 2017, all Daily events, previously only available on specific days, are available each day). Scissors Cavern, Inner Grotto was not a regular Friday event, it used to appear only on some special Fridays (also for 24h). Around late 2016/early 2017 it became available on each Friday. It has no rainbow boss, just two chances of catching regular plated lobsters (there is no rainbow plated lobster in the game - yet). It was retired around mid-2017/ From mid-February 2017, Innermost Grotto was added, featuring Rainbow Armored Crab.
- Friday Island provides Evolver Characters (crabs and rarely, lobsters, the latter only in the Inner Grotto).
- Since recently (early 2016) turtles can appear on Fridays, too. See Daily:Monday for details.
- For tips on how to clear this quest quickly, see tips on fast farming of turtles in the article on Turtles (as crabs and lobsters have similar high defense to turtles, same logic applies).
