I was reading the article on this site about Doki Doki Panic and SMB2(USA)
and I reliezed something: the story in DDP is that 2 kids are sucked into a
book. SMB2USA was the first Mario game to feature the Shyguys. Then, years
later, in Yoshi's Story, Yoshi and his friends are sucked into a book and
the game contains... you guessed it, SHYGUYS!!! Is that just an odd
coincidence, or did Nintendo do that dileberatly?
