All of their logos feature a dog.
They made separate logos for:
The 1989 game Keef the Thief: A Boy and his Lockpick for Apple IIGS, Amiga, and MS-DOS.
The 1991 Super Nintendo game Rings of Power
And the 1994 3DO game Way of the Warrior
They were the original creators of Crash Bandicoot (only the first three games)
Scare Factor Edit
Keef the Thief variant: Minimal, the logo looks tacky.
Rings of Power variant: Low, due to the dog barking.
Way of the Warrior variant: None to minimal, bordering on low.
1996-present: None to low, depends on the game.
