What is the status on these monsters

[99]

I want to know before I spend 10 minutes getting to a dungeon only to find that a monster doesn't exist/doesn't drop anything...

• Moss giants (In Varrock Sewers)
• Chaos Druids (In Taverly Dungeon and Edgeville Dungeon)
• Hill Giants (In Edgeville Dungeon)
• Skeletons (In Edgeville Dungeon)
• Hobgoblins (South of Falador and Edgeville Dungeon)

As far as I know Chaos druids do not drop herbs.
