As I reported in Apparently kid's don't watch enough TV the WB is planning on cancelling Kids WB on weekdays. This could have enormously bad consequences.
As we all know, due to an evil curse cast upon him by a cruel wizard, the Merch needs children to purchase Merch related products on a regular basis. He needs this even if it forces children's parents into unrecoverable debt. Otherwise he will become the hideous Fleshreaper (see above enormously bad consequences).
Thankfully, the men at Penny Arcade, unlike Kids WB, have got us covered.
Go and buy your Merch Merchandise now!
