Parolilo is the first machine soldier encountered in Rodea the Sky Soldier. Although it's modeled after a pufferfish, it doesn't have any spikes, but its red variant does. In the Wii U and 3DS versions, it's seen since learning how to boost attack in the prologue, however in the Wii version, you don't encounter any enemies until Chapter 2. Its movement pattern consists of moving back and forth on a pre-programmed path, and can do no damage to you unless you fly or fall into it without boosting. Because of its lack of spikes, it presents virtually no threat, and therefore is a perfect first enemy.
