The Doraemons: The Puzzling Challenge Letter of the Mysterious Thief Dorapin!

Plot

A mysterious blonde girl in a pink field keeps her identity hidden. The Brazilian robot cat Dora-rinho rushes to tell the Arabian robot cat Dora-med III about an urgent problem, though he cannot remember the specifics. He does recall that Principal Teraodai needs help against the globally wanted thief Dorapin. They fly to Teraodai's sky laboratory, nearly losing Dora-rinho during the trip, and meet their teammates: the American robot cat Dora-the-Kid with his robot pegasus Ed, the Spanish robot cat El Matadora, the Chinese robot cat Wang Dora, the Russian robot cat Dora-nichov, and their leader Doraemon. Teraodai, hiding from Dorapin, explains that Dorapin intends to steal their Bestfriend Telecards. Dora-the-Kid shoots at Teraodai, revealing he is actually Dorapin in disguise. Dorapin taunts them and uses a supermagnetic force to disable their gadgets. The Doraemons use their Bestfriend Telecards to briefly blind Dorapin, but he turns them into frozen gold statues. Dora-med III and Dora-rinho wake up in a dark void. Dora-med III realizes they have become gold statues. He accidentally pulls a tarot card instead of his Bestfriend Telecard, while Dora-rinho has a plain yellow card. Duplicates of both appear, and the Dora-rinho duplicates claim the real Dora-rinho holds the Bestfriend Telecard. Dora-med III tries again but gets a Hanging Man tarot card, which shows one Dora-med III upside down. Dora-med III warns Dora-rinho not to use his Bestfriend Telecard, but the duplicates urge him to. Dora-rinho deduces that the hanging Dora-med III is actually Dorapin in disguise. He kicks a soccer ball at Dorapin, exposing him and creating a hole in the wall. Dorapin makes all duplicates vanish, revealing his moustache can create duplicates, then flies away. Dora-rinho tries to chase but trips and falls. In Dorapin's lab, the frozen gold statues of the Doraemons are displayed as he thinks about how to capture Dora-med III and Dora-rinho for their Bestfriend Telecards. A shadowy figure pressures Dorapin for results, which he promises to deliver soon.
