Follow-up on the Invisible Mail

***Pre-recorded adventure***

Hullo... do you remember the Mystery Mail we got a while back? Well... we were pretty sure the blank piece of paper had invisible ink on it... probably lemon juice ink! Which gets revealed through heat.

So we tried a candle... nothing. We tried a blowdryer... nothing! Now we are pulling out the big guns... the iron!

Alright Cocoa... iron away!! And watch your tail!!! Nothing worse than a flat tail... (speaks the bear who has NO tail!)

Do you see anything?? I don't see anything!

Nope nothing!

OK... Ministry of Puzzles... was there another ink that was used? This mystery will have to remain unsolved for now... even though the fate of the world hangs upon us solving this! EEK!

TO BE CONTINUED (WE HOPE)
