Dungeons & Dragons - Hoard of the Dragon Queen
Discriminating companion to Spackles.
Tinker is the pet mouse, and closest friend, of Spackles. Tinker does not like many people, and he voices his opinion of others to Spackles regularly. Tinker is very loyal to Spackles, even returning to Spackles after being set free in the cellar so that he would be safe from the dragon attack in Chapter 1.
