Bubbles, Bugs, and a Spider

We thought that a bubble bath would be a really fun idea. Well...

You can see Kara's uncertainty here (she's on the left). She soon started screaming, had to be removed and wouldn't calm down until the bubbles were all gone (hard since Andrew accidentally dumped in a third of the bottle). Anna was fine but lost it when sister started.

The bubble story continues: the girls are apparently obsessed with their recent unpleasant/scary experiences. Every time they see bubbles in a book or hear the word bubble (or see the bottle, which had to be moved), they point towards the bath tub with a squeal of displeasure, and have to be reassured (and often have to go see) that the bubbles are all gone. Then they show me everything that we did with bubbles. Bubble shoes, bubble hat, mom had bubbles on her fingers and shook the bubbles off, etc. Repeat over and over and over. The bubble incident happened almost a month ago...

Bugs: there was one small potato-type bug near their toy box 3 weeks ago. Again, if a bug is mentioned or spotted in a book, they point to where the bug was (near our entertainment center) and wince, then need to go see that he's no longer there. They then proceed to show me how you smash a bug and stomp a bug. The bug actually got away before I killed it, so they show me the exact path that he walked and the exact spot where he ran under the entertainment center. This too goes on and on.

Lastly, our friendly spider. They like him for some reason. He lives in the closet and they love to go look at him and blow him kisses (and tell me they're going to play with his toes - another obsession of theirs from a book we have - everything they like they tell me they're going to kiss and play with their toes, even if I tell them it has no toes). Kara will stand at the closet door and yell at him until I come pick her up to see him. If we mention the spider, they will stop whatever they're doing to run to the closet and let me know I need to pick them up to see.

Is this normal? I'm glad they have good memories (sometimes better than mine), but seriously!
