Viking, By All Means

Suneo tells the other children about an all-you-can-eat buffet he experienced at a hotel, and gives them (except for Nobita) invitations to the buffet.

Nobita has no choice but to ask Doraemon for help. In order to help Nobita realize his wish, Doraemon takes out the "Anything Viking", resembling a Viking longship which can fit two people, also including two Viking helmets (with horns never present on historical ones). Doraemon demonstrates it by sitting in the longship, putting on one of the helmets, and going down to the living room where Nobita's mother is sitting. He asks her for some dorayaki, only to be told he has had enough for the day. Then, Doraemon declares into a speaker on the ship, "All-you-can-eat dorayaki!" and the cannons on the ship fire, releasing a pink gas which fills the room.

When the gas clears, Mrs. Nobi goes off to buy lots of dorayaki, then is subsequently confused about why she had done so. Doraemon explains that the Anything Viking can give one an "all-you-can-experience" buffet of anything. However, it can only fulfill 10 wishes at once, and wishes must be “stated specifically”.

Doraemon and Nobita take the Anything Viking out into the sandlot. Gian and Suneo spot them and laugh at them for playing with such a childish-looking setup. Doraemon and Nobita say into the speaker, "All-you-can-read comics!" Once the gas from the cannons have cleared, Gian and Suneo are back with bags full of comics, and are later puzzled by why they had to give Doraemon and Nobita their comics.

Doraemon and Nobita then use the Anything Viking to take all the transport they want, play with all the toys they want, play all the arcade games they want, eat all the food they want, and watch all the movies they want, all for free. By the time they return to the sandlot, only two wishes are left. Just then, Shizuka comes across them and Nobita takes the opportunity to explain the gadget to her. He tells her that she could, for example, say "All-you-can-take baths!". Confused, Shizuka repeats the sentence, only to be invited by strangers to bathe at their places. Shizuka is horrified and runs away.

Gian and Suneo snatch the Anything Viking from Nobita. They struggle to decide what to use the last wish for. Gian wants to sing as much as he wants, but Suneo dismisses this as too ordinary. Eventually, they decide to wish for "all-you-can-do anything" (nandemo kandemo yarihoudai, 何でもかんでもやり放題).

To Suneo and Gian’s bewilderment, after the gas clears, Indian chefs rush to them, offering them naan bread. As Suneo and Gian puzzledly hold the naans, a truck drives up to them and dumps a pile of empty drink cans around them. A filming crew then drives up to them, with actors dressed as Viking warriors, hurling spears at the director's command. The spears land all around Gian and Suneo, who run around in a panic, as they continue to be offered naan bread and showered with drink cans.

Thus, Gian and Suneo ended up with "naans and cans and stuff" (nan demo kan demo; ナンでも缶でも) and "as many spears as [they] want" (yari houdai; 槍放題).
