Role of Nester the baby lockness

Nester is for boys and girls 4-10 years old and for the curious (tear you toy apart to look whats inside 10-14yrs).  A typical user description below.

Billy turns 8 years old this year and his mother is thinking of buying him a cool toy.  He plays videos games, rides his bike and enjoys swimming as well.  His typical toys are action figure types as well as the typical laser guns and light saber swords.  Though Billy is 8 years old, he is afraid of the dark still.  He would prefer to have a soft toy that will make him feel safer in his room at night.  He is the only child so there is no younger or older brother to keep him company in his room.  Mom and Dad are getting tired of letting Billy sleep in their room when he hears creaking sounds of the house settlling.  His parents thing
Nester the baby Lockness would be perfect for him, as Nester is a plush to that can go wherever Billy goes
namely:

Refrigerator in the middle of the night for a drink of water
Restroom at night (he is scared of the toilet flush sounds)

Nester wakes up whenever Billy talks to Nester or squeezes his tail. Nester stays on for 3 minutes and slowly turns off giving Billy enough to to calm down and fall to sleep, use the restroom, or walk to the fridge.  Nester allows Billy to sleep in Peace as well as his parents.
