A Puppet with this ability is immune to the effects of the following moves:
- Perish Song
- Heal Bell
- Hyper Voice
- Binding Voice
- Nature Sound
Any of the above moves that would normally lower stats or do damage will simply do nothing to a Soundproof Puppet.
A Soundproof Puppet cannot be forced out of battle through Roar.
While a Soundproof Puppet may not be directly affected by Perish Song, they will still faint if they receive a Perish Counter through Baton Pass.
A Soundproof Puppet cannot have ill status cured by Heal Bell.
In Fire Red-based hacks, a Soundproof Puppet cannot be woke up by using the Poke Flute.
