It is Week 3 of Beyond Light, which means a new Penguin Souvenir is available in the game. You will need these for the Reuniting the Eventide Rookery Triumph if you want to go for the Splintered Title this season.
This little chap can be found in the Eventide Ruins on Europa but is a little more involved than the first two. The first thing you will need to do is find a new, powerful Fallen enemy that hangs out near the platforms in front of the elevator that leads to Riis-Reborn Approach.
He is armed with a Scorch Cannon that you will need. Head for the area where the public events tend to happen, then go up to the elevator. Instead of heading upward toward Riss-Reborn Approach, continue down that platform instead. The enemy can be found down there.
Kill him, then take the Scorch Cannon. Now, don’t just start blasting, you will need a round to get the Penguin Souvenir. Make your way towards the building that houses the entrance to the Bunker E15 Lost Sector and go inside. There are a few entrances, but you are looking for the one that leads up some steps, from a hole in the wall. Just before you go up the steps look to the right, and you will see a suspiciously shaped block of ice. Blast it with the Scorch Cannon to reveal the Penguin.
When you have it, you can head back to the room beside Variks and place it on the empty spot.
