He was about to say what it said, but Henry goes and yells 'Noooo!!!' while covering his ears, opening the title card. 
Henry soon asks about the hashtag and leaves but is stopped by Mum who tells him to spend quality time with Peter. In the fort, Peter, using his magnifying glass, informs that the interior of the fort is a mess. Peter asks about the mystery of the hashtag. Margaret is heard eavesdropping and Peter goes to see her followed by Henry.
Despite Margaret not watching the show, she owns two mobile phones. She is invited over to help solve the mystery.

He sees Margaret complaining about Peter finding the answer on the garden wall. Peter is told by Margaret to search up Number Gnome Number One. The two search up on the phones to find a hint.

Henry hides the tablet but Peter and Margaret hear it. Peter opens the cushion to find a new message on the tablet. Margaret read it but cannot understand it and gives up.
The #1 Mystery is soon solved. It turns out Peter was Number Gnome Hashtag One. Peter goes and calls Mum to tell her that they solved the mystery. A new message appears, and it says 'Who is Number Gnome No. 2'. Henry soon covers his ears again and screams 'NOOOOOOOOOO!', ending the episode.
