Is Tatsugiri damaged by its partner Dondozo’s Earthquakes?

Question

If tatsugiri is in dondozo’s mouth, and dondozo uses earthquake, will it also hit the tatsugiri in its mouth? In bulbapedia it says that any opponent moves targeted at tatsugiri will fail, but I didn’t found anything that says that tatsugiri is also out of reach from its ally dondozo’s attacks.

Answer 1

The tastugiri will go undamaged as it is in dondozo's mouth

Answer 2

Tatsugiri will go into Dondozo's mouth and be unable to be damaged from attacks. Dondozo can no longer switch out. Dondozo's stats all raise by 2 stages

Earthquake will hit all foes on the field, including allies.
Tatsugiri's ability will negate all damage (Aside from status damage, exp. Toxic).

So no, Tatsugiri will not be damage by it's ally Dondozo's earthquake (or any attacks in general).
