When Rita makes Crayfish and the mutants grow, the yellow and pink mutants have mysteriously disappeared.
At the start of the episode, Tommy tells Kim in the school hallway that he is late to class. Shouldn't Kim be getting to her class as well?
Why did Goldar destroy the Red Badge of Darkness? Couldn't he have just created another Putty?
During the morphed scenes, Black Ranger's Power Axe was missing its blaster mode handle and trigger except in the Power Blaster formation sequence and in the Command Center.
As the Rangers summonded Titanus for the Ultrazord, the Megazord symbol that is usually on the wall behind Red Ranger in the cockpit was missing.
When the Putties/Mutant Rangers were wearing the Badges of Darkness, the badges looked like the regular badges that the Putties usually wear.
During morphed Tommy and the Green Mutant's sword fight, the clone's Sword of Darkness could be seen bending when the two blades lock.
(Bulk and Skull approach Ms. Appleby dressed in tophats and suits)
Bulk: Skull! A gift for the lady! (Bulk has Skull hand Ms. Appleby a box)
Ms. Appleby: Why, thank you boys! I'm so glad to see you're taking this assignment so seriously. But if you don't mind opening the box for me? (handing it back) I just had my nails done.
Bulk: (Nervously) We don't want to deprive our lady the surprise of her gift!
Tommy: Come on, you guys don't give up now!
Skull: (sophisticatedly): Shut up, dweeb! Ha ha ha!
Ms. Appleby: Please, I insist!
(Bulk and Skull have no choice, they open the box and are covered in spray string, screaming as they run down the hall and everyone is laughing)
Ms. Appleby: Some people never change.
(Kimberly and Mutant Pink face each other)
Mutant Pink: Kinda like fighting a mirror, huh?
(#6 jumps into the air and flails, falling to the ground)
Goldar: NO! Number 6, leap THEN kick! Try again! (#6 flops about in the air and falls again)
Goldar: Training is complete! And I have made my decision. (points to Putty #6) You, #6, are going back to the clay jar on Finster's work bench! SEE YA!!
(he blasts #6 away with his sword)
Tommy: Man, I never thought of myself as forgetful. Do you think that I am?
Kimberly: Well... you didn't exactly remember your notebook at school today.
Tommy: I guess I've forgotten all the times I was forgetful, too.
Green Mutant: What's the matter, Tommy? Something look familiar?
Commander Crayfish: (After creating Mutant Ranger pyramid) Now we'll see who the shrimps are!!
Blue Ranger: They've raised the crayfish above our blaster's range!!
Black Ranger: So he can sit back there....
Blue Ranger: And fire on us at will! Jason, we've gotta get past his Mutant Rangers!!
Red Ranger: All right, we're goin' in!!
Red Ranger: (Readying Power Blaster) One cooked crayfish, coming up!
Commander Crayfish: (Readying Mutant Power Blaster) We'll see about that!!
Pink Mutant: (To Kimberly) Kind of like fighting with a mirror, huh?!
Blue Mutanty: I'm after you, Blue!
Yellow Mutant: Hey Trini, wanna play too?
Black Mutant: Nice to meet you, Zack!
Pink Mutant: Told you I'd be back!
Commander Crayfish: Is that the best you can do?!!
Green Ranger: There's plenty more where that came from, you over-grown seafood platter!!
The Rangers are given new, more powerful, (but completely identical to the originals) weapons to combat the Mutants with in this episode.
Rita's Sword of Darkness from "Green With Evil" (2) through (5) is the Green Mutant Ranger's weapon.
This is the final time Rita throws her Magic Wand to make monsters grow (In the next episode, Oysterizer seems to grow of his own accord).
The weapons the Mutant Rangers use look similar to the ones that were transformed into the Ranger's Power Weapons, way back in "Teamwork".
Commander Crayfish will return in next season's "A Reel Fish Story".
Second time this season that the Rangers have faced their evil doubles (after "A Bad Reflection On You"), but the first time Tommy has faced his. Tommy will later face himself again in the Season 2 episode "Return of the Green Ranger (1)". This is also the first time evil Ranger doubles grow giant-sized (Blue, and Black, and this is the second time an evil Green Ranger grew this season).
Final appearance of the original Ultrazord, and MegaDragonzord combo.
