- Looking at the creature from side on you can see that it has the child's ball stuck to its head, from the Witch's House quest. Even after you finish the quest they still have them on their heads.
- An experiment bone, which differs from the usual bones dropped by Experiment No. 2, are rare drops used in the Rag and Bone Man quest. This bone cannot be buried.
- When it attacks with Ranged, it throws the shrunk ogleroot that it has in its arm on its head. Furthermore, a shrunk ogleroot may also appear below you when it attacks with range, similar to how when you attack an enemy with a ranged attack, your ammunition will appear underneath it.
- If you go to the top of the chaos druid chamber in Taverley Dungeon, you can see the Experiment.
