Doraemon travels through time and becomes Nobita

"Doraemon, do you mean, where is your bell now?"

"If the clue magnifying glass is not malfunctioning, this should be it. I remember Doremi said she has a museum ticket."

Doraemon took out the phone from his pocket and called Doraemon.

"Hello, hello, is this my dear sister? It's me, Doraemon. I need a ticket to a museum. Can you come over? Okay, I will prepare a cake for you."

After hanging up the phone, Doraemon took back the phone and said.

"Nobita, go to the Rabbit Kingdom and bring back a piece of cake to treat Doraemon."

"Okay, Doraemon, wait here."

Doraemon took out the anywhere door, and Nobita put on the badge and shoes and came to the moon. He first went to the gathering place and took the celestial demon back to the system space. Looking at the two sleeping people, Nobita acted quietly without waking them up.

In the Rabbit Kingdom, Nobita found Nobita the rabbit and asked him to prepare a double-layer cream cake, on which Nobita asked him to write "For my dear sister, Doraemon".

After the emergency production was completed, Nobita and the several moon rabbits wore green badges and helped Nobita carry the cake over. Doraemon looked at the cake and said.

"Nobita, what you did is too luxurious. Next time you invite Doraemi, you have to treat her better than this. Otherwise, I, as her brother, will lose face!"

"It's okay, Doraemon. You can just keep stacking the cake layers. Thank you for your hard work. Please go back now."

After hearing what Nobita said, the Little Moon Rabbits bowed to the two of them and left. Doraemon put away the Anywhere Door, took out the Discussion Badge and waited for Doraemon to come.

After a while, Doraemon came out of the drawer, and Doraemon asked Doraemon to wear the badge of discussion.

"Brother, why are you wearing this?"

"Doraemi, you'll know once you put it on!"

After Doraemi put it on, she saw Doraemon and Nobita appear in front of her. There was a double-layer cream cake with a candle on it, and Doraemi could see clearly the words on it.

"Thank you, brother. Can I eat now?"

Doraemon took out a fork, knife and plate and handed them to Doraemon.

"Of course, it's prepared for you, ahem."

After learning the reason why her brother went to the museum, Dorami said while eating cream cake.

"Brother, there's no need to go all the way there. I'll go to Future Company and buy you a new one."

Doraemon said, shaking his head.

"No, Doraemon, I don't want that bell. Absolutely not!"

Doraemon said, "Brother, why are you so insistent about that bell?"

Doraemon blushed slightly as he looked at Nobita beside him and said, "Well... that's because, Doraemon, please don't worry about these details, okay?"

"I really can't help you. This is a gift ticket, but I went through a lot of trouble to get it, so I can't just give it to you for free."

Doraemon said carefully while holding the invitation ticket.

"I know Doraemi, next time I will send you 10 melon buns!"

"20!"

Doraemon looked at the proud Doraemon and said through gritted teeth.

"20.., okay I'll give you 20 melon buns."

"Brother, this ticket can allow five people to enter the museum."

Nobita said, "Doraemon, this is a rare opportunity, you should come along too."

"Not today, Nobita. There's a melon bag sale in the evening."

Nobita said, "That's a shame Doraemon, then Doraemon let's go find Fat Tiger, Suneo and Shizuka and ask them if they want to go together."

Doraemon handed the invitation ticket to Nobita and took out a random door from his pocket. Nobita opened the door and came to the open space, where all three of them were.

Fat Tiger said as he sat on the steel pipe.

"What do you have in your hand, Nobita?"

Xiaofu smiled and said.

"Nobita, what kind of outfit are you wearing?"

Nobita and his brother and sister walked out of the anywhere door, and Doraemon explained the general situation to the three of them.

"Since there is such a thing, as friends, how can we just stand by and watch, right, Suneo!"

Fat Tiger patted Suneo.

"Yes, yes, yes. Let's go to the museum and get the bell back."

Doraemon looked at the two and said, "Why do I feel like you just want to go to the museum..."

The two said they would definitely help, and Doraemon took out a pencil from his pocket and wrote his name on the invitation ticket, Doraemon.

After writing his name, a string of digital codes emerged from the coupon in Doraemon's hand, forming a car.

"The invitation ticket turned into a car!"

"Hahaha, that's so cool."

Suneo and Fat Tiger hurried over to check the car, Doraemon, Nobita and Shizuka also walked over. Nobita saw that Doraemon was acting strange and asked Doraemon in a low voice.

"Doraemon, look at what's going on with Doraemon. He looks a little weird. It feels like he's turned into a cat."

Doraemon said as he jumped all over the floor while Doraemon looked at him.

"That's because my brother has turned into a wild cat. If we didn't always carry the bell, he would gradually turn into a wild cat."

"Doraemon, how do we solve this situation?"

Doraemon said as he listened to Nobita's words.

"Actually, it would be fine if I just wore any bell, but my brother insisted on wearing that bell. I really don't understand what he insisted on..."

Nobita thought about the bell, but he really had no impression of it.

"Hey Nobita, what are you doing? Get in the car!"

Xiaofu said, "Hey, hey, hey Fat Tiger, just talk and stop pulling my hair!"

Nobita looked at the four people sitting in the car. Nobita sat in the passenger seat and Doraemon pressed the start button.

"The shuttle bus to the museum is ready, let's go."

"Spoken?"

Suneo and Fat Tiger stood up in the back seat and watched.

Doraemon said: "You two should sit down quickly, it's very dangerous!"

The shuttle slowly rose into the air and Doraemi looked up and said.

"Nobita, be careful on the road, and take care of melon buns too!"

Nobita nodded to Doraemon in the car, and the car started moving quickly and flew directly into the sky.

"It has been detected that the shuttle bus has reached the corresponding altitude and is now preparing to enter hyperspace. Passengers, please sit tight."

After the shuttle bus finished speaking, a hyperspace entrance opened in front of the bus, and the bus flew in through a time tunnel, and soon the bus flew out of the hyperspace, with Nobita holding onto his hat to prevent him from falling.

Doraemon said: "It's the 22nd century now. It's a familiar and nostalgic place."

The shuttle bus rang again.

"Dear guests, please look ahead."

Suneo said as he squinted his eyes and looked ahead.

"What is that, an island?"

The shuttle bus rang again.

"The building floating on that island is the Secret Tool Museum, the destination of this journey."
