1st Logo (1984)
Logo: A green speech bubble zooms out on a white background, as we see the text "ピップフジモト" in black below. Then the white "P!" appears inside the bubble, with the exclamation park slanted.

Technique: Cel animation.

Audio: A high-pitched "Pip!" sound when the "P!" appears.

Availability: Seen on a few Pip commercials from the time period, though most of them do not feature this logo.

2nd Logo (1980s-1990s)
Logo: We see the "P!" speech bubble logo from before near one of the screen corners at the endcap of the commercial. Then it grows quickly, taking much of the space of the screen, before shrinking back to its place again.

Variants:
 * Sometimes the logo grows more slighter.
 * A few commercials had the logo just appear at the end.

Technique: 2D animation.

Audio: The last seconds of the commercial, and the same "Pip!" sound from before.

Availability: Seen on Pip commercials from the time period.

3rd Logo (1990s)
Logo: We see a green shiny gradient take up most of the screen, before zooming out quickly into the speech bubble of the Pip logo. The "P!" then appears in front of the screen bubble, along with the black Japanese name below. It's basically a redesigned version of the 1st logo.

Technique: Computer animation.

Audio: The "Pip!" sound effect.

Availability: Seen on a few Pip commercials from the 1990s.
