How to make the Form 2 and three animate while the buttons are on form 1

Question

I want my form 2 and 3 to animate while the buttons are on form 1 and when it goes to form 2 it doesn't stop it continues animating.

FORM 1 CODE:

Public Class Form1

    Private runSequence() As Image
    Private walkSequence() As Image
    Private idleSequence() As Image
    Private runIndex As Integer = -1
    Private walkIndex As Integer = -1
    Private idleIndex As Integer = -1
    Private WithEvents trmRun As New System.Windows.Forms.Timer
    Private WithEvents trmWalk As New System.Windows.Forms.Timer
    Private WithEvents trmIdle As New System.Windows.Forms.Timer

    Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
        Form2.PictureBox1.Visible = False
        Form3.PictureBox1.Visible = False
        Form2.Show()
        Form3.Show()
        Me.Width = 300
        Form2.Width = 300
        Form3.Width = 300
        Me.Height = 300
        Form2.Height = 300
        Form3.Height = 300
        Me.Location = New Point(100, 100)
        Form2.Location = New Point(385, 100)
        Form3.Location = New Point(670, 100)
        runSequence = {My.Resources.sonic1, My.Resources.sonic2,
            My.Resources.sonic3, My.Resources.sonic4}
        walkSequence = {My.Resources.SONICWALK1_removebg_preview, My.Resources.SONICWALK2_removebg_preview,
            My.Resources.SONICWALK3_removebg_preview, My.Resources.SONICWALK4_removebg_preview,
            My.Resources.SONICWALK5_removebg_preview, My.Resources.SONICWALK6_removebg_preview,
            My.Resources.SONICWALK7_removebg_preview, My.Resources.SONICWALK8_removebg_preview}
        idleSequence = {My.Resources.SONICIDLE1_removebg_preview, My.Resources.SONICIDLE2_removebg_preview,
            My.Resources.SONICIDLE3_removebg_preview, My.Resources.SONICIDLE4_removebg_preview,
            My.Resources.SONICIDLE5_removebg_preview, My.Resources.SONICIDLE6_removebg_preview,
            My.Resources.SONICIDLE7_removebg_preview, My.Resources.SONICIDLE8_removebg_preview,
            My.Resources.SONICIDLE9_removebg_preview}

        trmRun.Interval = 100
        trmRun.Enabled = False
        trmWalk.Interval = 100
        trmWalk.Enabled = False
        trmIdle.Interval = 170
        trmIdle.Enabled = False
    End Sub

    Private Sub btnRUN_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRUN.Click
        trmWalk.Stop()
        trmRun.Start()
        trmIdle.Stop()
    End Sub

    Private Sub btnWALK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnWALK.Click
        trmRun.Stop()
        trmWalk.Start()
        trmIdle.Stop()
    End Sub

    Private Sub trmRun_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles trmRun.Tick
        runIndex = runIndex + 1
        PictureBox1.Left = PictureBox1.Left + 6
        If runIndex = runSequence.Length Then
            runIndex = 0
            Timer1.Stop()
            Timer2.Start()
        End If
        PictureBox1.Image = runSequence(runIndex)
    End Sub

    Private Sub trmWalk_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles trmWalk.Tick
        walkIndex = walkIndex + 1
        PictureBox1.Left = PictureBox1.Left + 4
        If walkIndex = walkSequence.Length Then
            walkIndex = 0
            Timer1.Stop()
            Timer2.Start()
        End If
        PictureBox1.Image = walkSequence(walkIndex)
    End Sub

    Private Sub btnIDLE_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnIDLE.Click
        trmRun.Stop()
        trmWalk.Stop()
        trmIdle.Start()
        Timer2.Stop()
    End Sub
    Private Sub trmIdle_Tick(ByVal sender As Object, ByVal e As EventArgs) Handles trmIdle.Tick
        idleIndex = idleIndex + 1
        If idleIndex = idleSequence.Length Then
            idleIndex = 0
        End If
        PictureBox1.Image = idleSequence(idleIndex)
    End Sub
    Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
        If PictureBox1.Left >= 275 Then
            Timer2.Stop()
            Form2.PictureBox1.Visible = True
            Form2.Timer1.Start()

        End If
    End Sub
End Class

The thing is I want it to animate on form 2 and 3 without having to put buttons on form 2 and three I want the sprite to be controlled from buttons on the form 1. And I want it to be like if I pressed run on form 1 before it goes to form 2 the continuing animation will be run or walk if I pressed walk before.
