"The Animal Shelter"
"The Ninja" is the fourth episode of Dan Vs.
Dan uncovers a ninja vendetta after his cookies are stolen by a ninja.
After the ninja stole Dan's cookies, he realized Elise was in the same town and began hunting her. When Dan told them that he had been attacked by a ninja, Elise at first didn't believe him, until he showed her the shruriken the ninja had thrown at him.
Elise explained that the reason that the ninja had stolen Dan's cookies was because the ninjas had taken an oath to never make sweets of their own.
Believing that the ninja would go after Dan to get to Elise, they disguised Chris as Dan because they felt that he would have a better chance of surviving than Dan if poisoned. Chris was later tranquilized, and later that day, the ninja challenged Elise to a duel: if Elise won, he would leave them alone. If Elise lost, he would kill her and go after Dan next. Elise went to fight the ninja and Dan followed her and helped her to defeat him. The ninja surrendered, and explained to them that his entire ninja clan was wiped out in a bus accident.
Dan forced the ninja to make him cookies, and doing so made the ninja (named Dave) give up being a ninja and open a cookie shop named Ninja Dave's Cookies.
- This is the closest Chris has ever gotten to finding out about Elise's Double life. While there are 3 minor times he could of found out, but didn't realize it.
- This episode marks the only time thus far, where Elise and Dan are on friendlier terms than normal. Agreeing with each other and going against Chris together is several arguments.
- This episode marks the first appearance of Ninja Dave and his cookie shop, which becomes a frequent hang-out for Dan, Chris, and Elise later in the series.
