Rock guide
By maximum weight, the Rock is the heaviest Trash item in the Bestiary: it tops out at 45.4 kg, first among 24 Trash entries, ahead of Basalt (44) and Stalactite (26). You need Magnet bait to pull one up, and the wiki lists it for any water. The range starts at 15 kg and ends at 45.4 kg, averaging 34 kg, and at 0.75 per kg the average catch is worth 35.5, fifth of 19 Trash entries by average value, between Rusty Bolt (39) and Destroyed Fossil (35). Base XP is only 10.
Two details come from the wiki. Dave Rod's passive guarantees this catch, and a version 60x bigger called the Boulder exists, with a 0.0001% chance (1 in 1,000,000) of appearing at Keeper's Altar.
The catch quips are all deflated, from “Ermm..?” to “Oh. A Rock.”, and the in-game text reads “It's not a boulder.. It's a rock!”
