Since time immemorial, video games have been known to hide little secrets here and there that are not always found during the first few playthroughs. This is especially true for open world titles that have sprawling maps with lots of discoverable areas. Games like Skyrim have a ton of interesting Easter eggs, including ones that sometimes reference other franchises. Minecraft is another example in which the developer can sneak something in that may not be uncovered for some time. In this case, it can take years for fans to unearth them.
User TidiToad posted a short clip to the Minecraft Subreddit a few days ago which shows them engaging in a light bit of fishing along with another player. During the usually tranquil activity, they are suddenly given a bit of a shock as an Elder Guardian comes lunging out from the small body of water to attack them. According to a report from PCGamesN, this is based off an April Fool's snapshot update that goes back to 2020, meaning that this rare Easter egg has seemingly gone unnoticed for two years.

In any case, it goes to show that no matter how long the game has been out, there are still opportunities to find new things.
