Caterpillar Friendly Tubes

The caterpillar actually has two friendly tubes so in many ways, this actually may make the caterpillar friendlier. Whether the number of friendly tubes actually makes a difference is subject to debate, but I believe more tubes = more friendly. The friendly tubes on a caterpillar are it's antennae. The reason its antenna are its friendly tubes is because the caterpillar uses the antennae to feel around and touch things to figure out if they are safe/danger, friendly/unfriendly. So if a caterpillar touches you with either or both of his antennae, that means he wants to be friends.

Interestingly enough, the entire body of the caterpillar is tubular in shape perhaps indicating that the caterpillar is one of the friendliest creatures out there. Please do not say anything about snakes, otherwise it will ruin my point.
