Season 2 Continuity

Inanimate Insanity II Episode 1: "Breaking The Ice" explained many unrevealed occurrences in Season 1, as well as bridging the plot hole between seasons.

Continuity

 * OJ bought a hotel, labeled fittingly "Hotel OJ". It is located near orange trees, a sidewalk, and mountains similar to those in the Mushroom Kingdom from the Mario series. It might even be away from the island that Season 1 took place on, but this is not confirmed.
 * Inside, OJ hosted a big party inviting all Season 1 contestants except for Taco due to her absence and possibly for her behavior in Journey Through Memory Lane (Part 2), Bow due to her death, and Balloon due to the fact that everyone hates him.
 * Paper and OJ tore Apple away from Idiotic Island 2.
 * Apple and Marshmallow are still enemies and Balloon still hates OJ and Pickle.
 * Salt and Pepper have rejoined together as BCFFs, Bomb trusts OJ since he jumped into OJ's arm when he was scared, and MePhone4 still hates Bow.
 * Adam gave MePhone4 a new assistant, Toilet.
 * Bow legitimately died by electrocution in the finale last season.
 * Balloon decides to say "actual stuff" again since he joined Season 2. This refrences to him having to re-use his lines after the previous voice actor was fired.
 * MePhone4 doesn't allow contestants to quit.
 * Apple is still "definitionally challenged."
 * If a contestant dies, MePhone4 simply presses a button on himself to regenerate them. It is assumed that MePhone4 regenerated the contestants off-screen throughout Season 1. Note that he can not regenerate Bow.
 * According to Toilet, Adam gives the staff lunch breaks.
 * MePhone4 encourages violence during challenges.
 * Baseball is still sensitive about his weight.
 * Baseball and Nickel are still agitated by their lack of arms.
 * Voting now takes place at official website instead of the comments.
 * There are new voice actors.
 * Lightbulb has either read or watched TROOS (The Rules Of Object Shows) As she follows them a lot.
 * Cheesy was revealed to be alive, as after getting run over by MePhone4S, he hadn't been seen until now.
 * Fan has more of an obsessive personality and likes II even more.
 * Lightbulb still has the habit of saying OMGA, which supports her wacky attitude.
 * Bomb, OJ, Paper, Pepper, Pickle, Salt and Taco were removed from the intro.
 * Bow wasn't still added to the intro yet.
