The winning team was concluded as the Blue Team as expected by many players, having maintained a significantly higher score than any of the other teams. The Green Team notably came in 4th place, only 1 point off from being tied with the Yellow Team in 3rd place.
Prior to the party on May 1, 2014, Polo Field posted a picture of himself on Twitter wearing a Beta Hat. Behind him was a whiteboard, with the words "UIN CUP" written (his hat was blocking the start of the word ending with "UIN").
It was referenced in issue #104449 of the Club Penguin Times during the Future Party about taking a trip to the past: "You may want to visit the first ever Penguin Cup, but you'll be a bit too early for this historic occasion".
On June 21, 23, 25, and 27, Aunt Arctic gave players an update on the tournament when they logged in.
One of the possible sounds that would play when scoring a goal at the Stadium during the party, played a siren sound effect which resembles the one of the Goal! mini-game from Club Penguin: Game Day!.
On the first day, on the "Equip" button on the Penguin Cup Ball, there was a member logo, implying it was for members. However, anyone could equip the ball. The member logo on the ball was eventually removed.
When you beat someone that is on the same team as you they turn red.
When you pick "Games" on the Map and pick Hydro Hopper, the arrow will be on the right of the Hydro Hopper.
When you click the ball above the penguin that wants to vs and then quickly change rooms, you will have 2 matches. The first is using the penguin with no music or sound and the second is using a bot that does not do anything.
When you enter the game after June 29, there is a chance that Aunt Arctic says "**w.p2014.soccer.dialogue.update.5.undefined**". The trophy will also rapidly change colors for each team.
