Why didnt episode 5 take place in the dark

[mikey22]

finishing up the pilot series today.. and was curious.. episodes 1,2,3,4, all took place mainly at night.. why did episode 5 have a mid afternoon feel? i enjoy watching episodes 1,2,3,4 more at night because they take place at night.. feels like more of an edge takes place

i wonder why the final and most important episode of the pilot series takes place during the day.. also wish they could have had a better fight with raph and shredder instead of just the quick "snap it up donatello" and poof hes done fighting him in 2 seconds of animation
