Pest and Spud! REGRETEVATOR BUCKETBETTLE

Pest has a blocky build, mainly resembling a 2011 Roblox Guest. His face texture features a devious grin with two sharp red eyes and red accent lines below and above the eyes, giving the impression of slight eye bags and brow creases. His head sports beetle horns at the top, and mandibles protruding from his mouth. His teeth are sharp and white, as seen when grinning.

In Pest's Halloween outfit, the letters "吸血鬼!!" appear on the back in Japanese, which translates to "VAMPIRE!!" in English.

All of his body parts are black with his head having a black shadow on top. On the front of his upper body is the word "Regret" in Japanese hiragana (こうかいする, Kō kai suru), and on the back of his torso are the words "Do you regret your decision?" also in Japanese. (自分の決断を復悔していますか?) The numbers "1314" in red are vertically placed on his left arm. He also sports a modified version of the Roblox "R" Baseball Cap, with the R slightly rotated to the right and replaced with a P instead.

In his previous appearance, he wore a shirt with the Japanese Roblox logo (ロブロックス, Roburokkusu), and on the back of the shirt, there was the inscription "make a free account to change how you look!", also in Japanese. (見た目を変える ためにフリーのアカウントを作りましょう! ) The word "guest" (ゲスト, Gesuto) in red was vertically placed on his left arm. He used to sport the default ROBLOX 'R' Baseball Cap.

Mainly greedy and sassy, Pest most of the time apologizes doing bad things.
