bot.js

//The twitter bot is mimicking an interactive pet. In the beginning, the project to me was very bland. 
//The idea of creating a twitter bot in itself was very cool but the majority of what twitter bots 
//actually do are mostly the same, mimic a celebrity or person, automated retweets and likes, and maybe 
//automated images for something more interesting. It was challenging to figure out a way to put my 
//personality into this project. However, perhaps it was due to the large amount of pet games I play and 
//my interest in cute things, I got the inspiration to create an interactive pet through twitter. 
//
//Mochi Pufflet is what I call my interactive pet. It has five distinct moods. Happy, hungry, sad, bored, 
//and unfortunately dying. Mochi expresses its emotions periodically through a status update and an image 
//(self-drawn). The audience can then care for Mochi by replying to it and using the keywords “food”, 
//“play”, and “love”. These mentions will be processed and increase Mochi’s condition as well as thank 
//the mentioner who cared for it. 
//
//https://twitter.com/mochipufflet
//The interval was set to a minute to quickly show how the twitter bot updates and interacts with other 
//people. However, the actual interval will be an hour long.
