The day henry met... a child kidnapper

So... my 4 yr old cousin was watching nick jr until the day henry met appeared, i thought this show's crap. But with closer inspection, the show probbably had a weird lore that i don't get.

The show started, my family was going to the supermarket. And i stayed taking care of her, then it appeared.

The day Henry met... A child kidnapper

My jaw dropped and i scratched my eyes and yes, it was the real title.As the episode started henry's mom said: Hey henry? stay here for a minute i'm going to talk to a friend of mine. Then a van appeared and said:

Hi Henry! Henry responded with another hi, soon been taken away and blindfolded. He tried to scream, but his voice was soon folded as well. His mother looked in shock, to see a van depart with his son behind the van.

My cousin asked if it was his dad, but i turned the television off and said it chrashed. Just to try to hide any trauma from her, but i couldn't help to record the episode and watch it later at night. I was shocked, and needed to know what the hell was going on with the producer's mind!?
