Gump Tooltip help

So I have a "Stabled Pet List gump" (see screenshot below) that I used the AddMobileProperty(pet) method to make a tooltip appear when hovering over the pet image tile button. I've also tried the AddTooltip(...) method which works if I give it a cliloc, but not if I give it a string (even though supposedly that's a valid method). What I'd like to do is override the default tooltip (in whatever way works or works best) with a different one. You can see the default from AddMobileProperty(pet) in the screenshot below and then I've included a screenshot of my leashed "shrunken pet" gump that I would rather use instead.

Any and all help for the best way to implement this is greatly appreciated!

public override void AddGumpLayout()
{
    AddBackground(0, 0, 500, 550, 40000);

    AddHtml(50, 12, 400, 18, Color("#FFFFFF","Stabled Pet List"), false, false);

    AddHtml(50, 38, 102, 18, Color("#FFFFFF","Click to Claim"), false, false);
    AddHtml(162, 38, 102, 18, Color("#FFFFFF","Name"), false, false);
    AddHtml(274, 38, 61, 18, Color("#FFFFFF","Bonded"), false, false);
    AddHtml(345, 38, 102, 18, Color("#FFFFFF","Type"), false, false);

    if (Index < 0) Index = Pets.Count - 1;
    if (Index >= Pets.Count) Index = 0;

    int start = Index;
    int index = 0;

    for (int i = start; i < start + PerPage && i < Pets.Count; i++)
    {
        BaseCreature pet = Pets[i];

        Rectangle2D bounds = ItemBounds.Table[ShrinkTable.Lookup(pet)];
        int y = 65 + (index * 75);

        AddImageTiledButton(50, y, 0x918, 0x919, 0x0, GumpButtonType.Page, 0, ShrinkTable.Lookup(pet), pet.Hue, 40 - bounds.Width / 2 - bounds.X, 30 - bounds.Height / 2 - bounds.Y);
        AddMobileProperty(pet);

        AddHtml(162, y, 102, 72, Color("#D5D5AC",pet.Name), false, false);

        AddHtml(274, y, 102, 72, pet.IsBonded ? Color("#74C365","Yes") : Color("#E50914","No"), false, false);

        AddHtml(345, y, 102, 72, Color("#D5D5AC",FriendlyNameAttribute.GetFriendlyNameFor(pet.GetType()).ToString()), false, false);

        index++;
    }

    if (Index + PerPage < Pets.Count)
    {
        AddButton(430, 510, 30533, 30533, 2, GumpButtonType.Reply, 0);
        AddHtmlLocalized(355, 510, 70, 20, 1114514, "#1044045", LabelColor, false, false); // NEXT PAGE
    }

    if (Index >= PerPage)
    {
        AddButton(50, 510, 30533, 30533, 3, GumpButtonType.Reply, 0);
        AddHtmlLocalized(90, 510, 255, 20, 1044044, "#1044044", LabelColor, false, false); // PREV PAGE
    }
}
