You’d think they’d wait one day in order to release it on 4/20, but the new stoner comedy “Pretty Stoned” (MTV, 8 p.m.), about a missing $20,000 payment to a drug queen-in, premieres tonight. Its twist is that instead of being led by dudes, the flick is led by women, and stars Paris Berelc, Pretty Wee, Tabatha “Dream Doll” Robinson, Kandi Burruss and Brandee Evans. It doesn’t look very good, but at least it beats another night of “Ridiculousness” (MTV, 9:50 p.m.). 

Past stars from the 30 year old franchise — named for their color-coordinated jumpsuits and helmets — join the anniversary special “Mighty Morphin Power Rangers: Once & Always” (Netflix, streaming), a combination reunion and new adventure. 

Speaking of old franchises, “The Mandalorian” (Disney+, streaming) ends its third season.

After six seasons, the drug drama “Snowfall” (FX, 10 p.m.) comes to an end with a series finale. 

Dr. M. Sanjayan’s Earth Day project “Changing Planet” (PBS, 9 p.m., check local listings) returns for a new season, revisiting six of the earth’s most vulnerable ecosystems and tries to figure ways to save them. 

“Home in a Heartbeat with Haley Alix” (HGTV, 9 p.m.) is a new renovation series in which Galey Alix and her team help deserving families reimagine their homes.

“Abbott Elementary” (ABC, 9 p.m.) ends its second season with a trip to the Franklin Institute.
