|First appearance||Bubble Bobble|
|Notable members||Madame Rubblen|
Rubblen, known as Rascal (らすかる Rasukaru?) in Japan, is a recurring enemy in the Bubble Bobble series. Like Baron von Blubba, Rubblens appear if Bub and Bob spend too much time in a Secret Room. They are usually invincible.
Rubblens do not have many abilities outside of being fast. They can move through walls, much like Baron von Blubba.
Rubblens first appear in Bubble Bobble, appearing when Bub and Bob spend too much time in a Secret Room. They move around the stage, pursuing Bub and Bob relentlessly.
Rubblens make their second appearance in Bubble Symphony, appearing once again in the Secret Rooms.
A Rubblen is the ninth opponent faced in the Vs. Mode of the SNES version of Bust-A-Move. Unlike most Rubblens, this one is blue.
Rubblens appear once again in Bubble Memories. As usual, they appear in Secret Rooms. They are transparent in this game.
Rubblens recieve a minor redesign in Bubble Bobble: Old & New. They look more cloudlike, and have an angrier expression on their face.
Rubblens appear in Bubble Bobble Double Shot under different circumstances than before. If Bub, Bob, and Bubu take too long to defeat a boss, a Rubblen appears to hunt the trio down. A giant Rubblen appears in a Continue Minigame, chasing Bub through a prison-like area.
Rubblens appear in Secret Rooms once again in Bubble Bobble Plus!. The boss of Expert Mode 2 is a giant Rubblen with arms and legs named Madame Rubblen.
- Rubblen originally appeared in the Taito arcade game Ben Bero Beh, under the name Hiyoshi-san the Rascal (日吉山のラスカル Hiyoshi-san no Rasukaru?). In said game, Hiyoshi-san the Rascal had arms and legs, a feature which was referenced in Bubble Bobble Plus! through Madame Rubblen's appearance.
- Rubblen's Japanese name, Rascal, is partially a reference to the enemy's shared behavior with Baron von Blubba, as the characters "sukaru" (すかる?) at the end of "Rascal" are shared with the first characters in "Skel-Monsta". This is further emphasized by "Rascal" being spelled in Hiragana in the Bubble Bobble series, rather than the usual Katakana used for the word "rascal" (ラスカル?).
