While the other New Mutants were studying for their mid-terms, Wolfsbne & Cypher were trying to teach Bird-Brain to speak English. Magik grew angry when they continued to use her as an example, and popped her bubblegum. Wolfsbane transformed into a wolf, and Bird-Brain reacted excitedly calling her a like-creature. However, he then flew at the window, and began making such a commotion that Cannonball had to drag him back down to the floor. Cypher translated Bird-Brain's squawking; a few phrases about a full moon, testing, and blood. He briefly settled down in front of the television, but grew agitated again when he saw pictures of Big Bird on Sesame Street with a tiger. Mirage changed the channel and Bird-Brain grew excited when he saw an advert for McBurgers. Magik teleported away and bought a meal to tempt Bird-Brain with. He wasn't allowed to eat anything until he was able to pronounce it in English. When he succeeded in saying Burger, Fries and Chocolate Shake, Bird-Brain received hugs from Cypher & Wolfsbane. Wolfsbane then hugged Magik for breaking the rules to help them.
The next morning Bird-Brain was stealing their donuts, while the New Mutants studied books and maps for ideas where he came from. The original new reports stated that he had been found in the North Atlantic, but he had recognised a Tiger on the television. Bird-Brain threw away pictures of animals in the zoo, but hugged books with pictures of Greenland. However, Mirage ordered them to let it wait until their exams had finished. The others began to study while Wolfsbane & Cypher continued to work with Bird-Brain. They established that he had no concept of numbers; only 'one' and 'many'. When he asked for many burgers, Magik teleported them to a local burger bar. When Cannonball returned to their table with a tray full of food, Bird-Brain grew restless again so Magik teleported them back home.
That night they watched a programme on television about a lion tamer. When the man used a whip against his lions, Bird-Brain grew upset again. They calmed him down by taking him to Cypher's room where they dressed him in one of Cannonball's old uniforms (Magik cut a hole down the back to make room for his wings). They pulled out a space mattress for Cypher to sleep on, while Bird-Brain had his bed. However, in the night Bird-Brain smashed through the window crying for his 'many friends'.
The five remaining New Mutants began to plan what to do. Meanwhile, Bird-Brain flew to the McBurger restaurant they'd been at earlier. There he asked for many burgers, friends and chocolate shakes. The staff were so afraid that they gave him as much food as possible. Not realising he'd stolen the food, Bird-Brain few off. The New Mutants caught up with him in mid-air, where Mirage caught him in a lasso. Magik caught the falling food, while Cannonball brought Bird-Brain crashing back down to Earth. Realising how odd it was for him to have so much food without eating, Mirage used her power to create images of what Bird-Brain desired. They say an image of a island with a steep cliff-side. Bird-Brain called to his friends on the island. Then the image changed to monstrous faces, which scared Bird-Brain. The illusion changed again, to friendly animal faces and a McBurgers meal. The New Mutants finally understood that Bird-Brain was trying to take food back to his friends on the island he'd escaped from.
The New Mutants considered what to do next. Wolfsbane was so determined to help Bird-Brain that she didn't care when Magik teased her about breaking Magneto's rules. So they all teleported into an area of the North Atlantic. There they flew around on Brightwind until Bird-Brain located his home island, Paradise.
It was still the middle of the night, and in the darkness they could hear strange hissing and rustling noises. Slowly, strange animal creatures surrounded the New Mutants...
