Pygame draw multiple/duplicate sprites same class

Question

The Problem: I want to add the exact same Sprite (it's a 25x25 white box) behind another one

the Sprite starts off at x,y 300,300 I have key functions that allow the Sprite to move in any direction

Let's say, that I move my Sprite to x,y 150,210... how do I grab that NEW position of that original Sprite, and then draw a copy of that Sprite directly "behind" that Sprites new position of x,y 150,210?

The end result is:

• there are TWO 25x25 squares together.
• On keypress, the two squares should always stay together. The "TWO" could be 10 or 20 or 40 squares at any point
• I do not want to increase the height of the sprite as a solution, I explicitly want a copy of the sprite

Please let me know if this question requires better context etc. Thanks in advance

Minimal reproducible example

import pygame
from random import randint
from sys import exit

pygame.init()
game_active = True
clock = pygame.time.Clock() #an object to track time

def display_surface():
    disp_surface = pygame.display.set_mode(size = (610, 700))
    return disp_surface
disp_surface = display_surface()

class square(pygame.sprite.Sprite):
    def __init__(self):
        super().__init__()
        image1 = pygame.image.load("square1.png").convert_alpha()
        x_pos = 300
        y_pos = 300

        self.image = image1
        self.rect = self.image.get_rect(x = x_pos,y = y_pos)

squaregroup = pygame.sprite.GroupSingle()
squaregroup.add(square())

while True:
    for eachevent in pygame.event.get():
        if eachevent.type == pygame.QUIT:
            pygame.quit()
            exit()
        
        if eachevent.type == pygame.KEYDOWN and eachevent.key == pygame.K_SPACE:
            game_active = True

        keys = pygame.key.get_pressed()
        events = pygame.event.get()
        
        left = keys[pygame.K_LEFT]
        right = keys[pygame.K_RIGHT]
        up = keys[pygame.K_UP]
        down = keys[pygame.K_DOWN]
     
        if left:
            squaregroup.sprite.rect.x -= 1
        if right:
            squaregroup.sprite.rect.x += 1
        if up:
            squaregroup.sprite.rect.y -= 1
        if down:
            squaregroup.sprite.rect.y += 1
    
    if game_active:
        disp_surface = display_surface()
        squaregroup.draw(disp_surface)
    
    else:
        disp_surface.fill((64,64,64))

    pygame.display.update()
    clock.tick(60)
