pygame animate 2 images while moving

Question

so i am currently working on a FNaF styled game i and want to animate 2 images like a gif while i can move the image with my mouse. i have figured out how to move the image already but the animation is a different story. help would be apreciated. heres my code

import pygame
from sys import exit
import time

pygame.init()
FPS = 60
clock = pygame.time.Clock()
#screen = pygame.display.set_mode((768,128*3))
screen = pygame.display.set_mode((1536,768))
pygame.display.set_caption('FNamH')
office_frame_1 = pygame.image.load('fnamh_office.png')
office_frame_2 = pygame.image.load('fnamh_office_2.png')

#office = pygame.transform.scale(office_frame_1,(1440,128*3.3))
#office_2 = pygame.transform.scale(office_frame_2,(1440,128*3.3))
office = pygame.transform.scale(office_frame_1,(2880,840))
office_2 = pygame.transform.scale(office_frame_1,(2880,840))




while True:
    
    
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            pygame.quit()
            exit()
    mx, my = pygame.mouse.get_pos()
    screen.blit(office,(mx*-1,my*-0.1))
    screen.blit(office_2,(mx*-1,my*-0.1))
    pygame.display.update()
