This is a 555 timer circuit which has an additional diode connected in parallel with the second resistor. This diode allows the off time for the LED to be greater than the on time. The buttons on Lisa's costume flash on briefly in a sequence, then stay off for about five or six seconds.
Resistors: R1 = 110K
R2 = 738K
C1 = 10 microfarads
