Echo-Bot needs to gather evidence about Wormhole's evil schemes.
How does Echo-bot gather evidence.
Do you remember Echo-Bot's core component, from the introduction? If not, look in its inventory.
I need a spoiler about how to gather evidence.
Use the Vox Recorder on Wormhole to gather evidence.
There is nothing to record.
You have to catch Wormhole having two conversations.
I need a spoiler about the conversations I need to catch Wormhole having.
One conversation happens at the Universal Machine. The other happens outside when Wormhole is talking to Merkley. Use the Vox Recorder on Wormhole only when he is in those two locations.
What's next?
Henry and Mum need the Vox Recorder. Somehow, Echo-Bot can just chuck it to them. Use the Vox Recorder on Henry and Mum.
What's next?
Where would Wormhole throw things away? And how could you pop the bubble with a discarded item? (This is another puzzle which makes more sense in retrospect, in my opinion.)
I need a spoiler about what to do.
Can you see anything that looks a bit like Echo-bot? There have been multiple clues (in game) about it, interestingly.
I need a spoiler about what looks like Echo-bot.
Interact with the Inconspicous Bin. Wormhole will throw an item into Echo-Bot.
