Hidden Song in Ascension
Once all 3 teddy bears are found, [like the meteors in Kino or the Telephones in Five the song Abracadavre by Elena Siegman plays. The first Teddy bear is in the Centrifuge Room upstairs on some barrels next to the Olympia. The Soviet Star Teddy is found in the Claymore Area by the lunar lander on the gate [move to lunar, turn around, head right.] The third Teddy is found in the Sickle/3rd Lunar Lander on top of a wall.
