On disc 1's setup menu, highlight the smiling cartoon man doodle, which takes you to the "Yohe Doodle Dandy" page. As soon as you enter, the audio kicks in explaining when and how Tom Yohe created the art for the show. The page includes four sketches and one photograph of Tom Yohe. Clicking on each picture takes you to a page showing the art doodles on a script or the sketch of the segment with music from the song.
On the disc 2 the main menu, highlight the water fountain on the right wall. Press your Enter button, which will cause the fountain to flood the hallway. You'll then see the turtle from the "Unpack Your Adjectives" song and the S.S. Ark with Noah from the "Elementary, My Dear" song as the water drains.
On disc 2's main menu, on the left side on the hallway, highlight the light switch, and press your Enter button. The animation shows the hallway in a blackout, followed by children's little white eyes looking around, and the skeleton from the "Not So Dry Bones" appears, which scares the kids, except one, who turns on the lights. After the skeleton sees the little girl he screams and runs away.
On disc 2's main menu, highlight the word "Credit" from the "Extra Credit" banner at the top of the hallway. By clicking enter you are taken to credits page for each song, plus 4 or 5 devoted to consultation credit pages. There are around 59 in total.
