The Wild Brood came there and complemented his espresso. Chen enjoyed the compliment but demanded they left because they were scaring away his other customers.
Later, when the gang were there, Mr. E sent them a clue over the internet of a dancing swordfish. Velma Dinkley correctly interpreted the clue and hacked into a site, but then she and Scooby-Doo were kidnapped by the Shadowy Orc.
