Ideas:Mission/EPF to the rescue!

Every penguin is kidnapped by Herbert and the EPF is here to the rescue!

Spoiler

 * You start at the command room. Go to the Pizza Parlor and ask for a Fish Dish pizza. Then bring it to Gary, Buy another pizza, but this time 10 boxes of Cheese Pizza. Don't bring it to Gary! Instead, go in the Command Room and get your mission.

After that, eat a slice of pizza and give a box to Jet Pack Guy, then, tell him that he needs to go to the Beach to buy a souvenir from the Migrator. Then ski down to the Test run. After that, you'll see Cadence and tell Rockhopper to go to the Mine, and build an elevator so he could go up.

Eat another slice of pizza, then go to the Ski Lodge. No one's there. Look in the VR Room and look for Gary. Gary said Rockhopper needs help and go to the Mine. Arr! Help me here! Oh, Rockhopper really need my help! Then after you play Cart Surfer.

Afterwards, go everywhere, until you go to Herbert's Camp. Call Klutzy and Flare.

Go to the cave where Herbert lived. Get the crowd to the Town and the mission ends.
