I want to make a grid container that can hold ice floats & water tiles. The ice floats are also containers that can hold fish and penguins. My idea was to make the whole game board a grid container, and then add ice float grid containers randomly, each with a panel child component that is the ice float texture,(same with the fish). However, when I add textures to the ice floats nothing shows up, and the fish float texture is just showing up in the corner of the screen.

extends Node

const GRID_CONTAINER_PATH = "PanelContainer/GridContainer"
const ICE_CONTAINER_PATH = "res://sr20f220030d8aws3.webp"
const GRID_COLUMNS = 8
const ICE_IMAGE_PATH = "res://iceblock2.jpeg"
const PENG_IMAGE_PATH = "res://sr20f220030d8aws3.webp"
const FISH_IMAGE_PATH = "res://fish.webp"
var fish = fish_image_tile(FISH_IMAGE_PATH)
var watertile = Panel.new()
var icetile = create_image_tile(ICE_IMAGE_PATH)
var icecontainer = GridContainer.new()

func _ready():
    var container = get_node(GRID_CONTAINER_PATH)
    
    if container:
        container.columns = GRID_COLUMNS

        for child in container.get_children():
            child.queue_free()
            
        for i in range(64):
            var min_value = 0
            var max_value = 25
            var min_value2 = 0
            var max_value2 = 100
            var random_int = randi() % (max_value - min_value + 1) + min_value 
            var random_int2 = randi() % (max_value2 - min_value2 + 1) + min_value2
            
            if random_int < 10:
                container.add_child(watertile)
                print("water printed.")
            else:
                container.add_child(icetile)
                icetile.add_child(icecontainer)
                var tile = create_image_tile(ICE_IMAGE_PATH)
                container.add_child(tile)
                print("ice printed.")
