PBS Kids

1st logo

 * Normal Versions: Low to medium. The loud singing and flashing patterns may scare some viewers. Nevertheless, this logo is well-liked by people who grew up in the '90s. But it's also one of the most annoying logos ever, thanks to the music, which is very, very catchy to the point of getting stuck in your head and never wanting to leave.
 * "Surprise!" Variants: Medium to high. The sudden appearance, the fast zoom-in and the P-Pals yelling "Surprise!" along with the same things from the normal version may spook more than a few viewers. The short version starting with the zoom-in through the door will also likely jumpscare many people.

2nd Logo
Low to medium. Those used to seeing the 1989 PBS logo or the P-Pals may be surprised to see this one.

3rd logo
None to low. Most viewers may find the music and visuals fun and entertaining, or even nostalgic. However, older viewers who preferred the older logos may find these kind of boring or also annoying.

4th logo
None, unless you're scared of the animated variants.

5th logo
None to low. Some people may be scared of the music and the kids' heads, but it's quite harmless.
