>>51574178Thing is that according to its official classification, Wiglett IS a garden eel, but Diglett is not categorized as a worm, rather as a mole. Considering that Diglett learns claw-related moves, it is extremely likely that it at least has claws underground.
>>51574284It does not look like a mole, but there's a high probability it does burrow like a normal mole would. Just because you can't see its claws it doesn't mean it doesn't have any, they're just underground. There's the fact that it learns shit like Shadow Claw, Scratch, Slash, Metal Claw, etc.
