That giant anglerfish.
[ul]4 sizes (0.3x small, 1x regular, 3x big, 7x bigger)[/ul]
[ul]Toggle ball via skins[/ul]
[ul]Toggle spikes via bodygroup[/ul]
Things to note
[ul]Model can sometimes cause Gmod to slow down (for me at least.)[/ul]
[ul]It is better to grab the chest and stomach by its back, since the majority underneath the model has no collision.[/ul]
Thanks to Dragoshi1 for providing the model.
Also on Toybox.
