In the episode "Bust a Move", two of the blues are briefly shown shaking their behinds in front of two female hatchlings. The female hatchlings get shocked and a male hatchling covers the eyes of one of the girls.

In "First Love", a female hatchling falls in love with one of the blues and keeps chasing him. In the end, she falls in love with a bug.

Some accidents, hatchlings sometimes hit each other and some pain but nothing serious.

In the episode "Sprung Out", one of the blues tries to order a spring several times but the delivery won't get it right and the last box that arrived included symbols that somewhat resembled a bad word replaced with different symbols.
