# Forum:Changes to pet Polytrap behavior?
&lt; Forum:Watercooler

Hey guys, has 3.6.1 made changes to pets around polytraps? Or maybe just on NAO?
1. I had a pet repeatedly jump on a polytrap intentionally.
2. After using a Magic Whistle to mutate a couple pets, it stopped working but still showed on screen. I should search and see if screen hasn't updated maybe? Used to be polytraps only disappeared when player used them.
Thank you!

What did they turn into? Some monsters may resist the polymorph effect. Notably, gray dragons can't be polymorphed by traps at all.  -- Andrio Celos (talk) 11:28, 4 November 2018 (UTC)
Thank you, Andrios. Even dogs and cats (with 0%MR) were landing on the trap and not transforming...unless they were transforming into identical dogs and cats!...maybe. Maybe they're also dodging the trap, just as a pit and landmine can be avoided (maybe i'll code-dive for that). In general, there just seemed to be a lot less pet-poly happening on the poly-trap than in the old days...but maybe it's my imagination. Thidwick (talk) 01:46, 7 November 2018 (UTC)

I play 3.6.0, and pets dodge polytraps a lot. My personal record is a wumpus that had to be whistled onto the trap 12 times before it would change. I always expect to burn several hundred turns to get the pet I want (Jabberwocks and Mindflayers are awesome!).--Skrizzle (talk) 02:51, 8 November 2018 (UTC)
I was wondering similar issue when trying to polymorph my pet who had been blue dragon already. But found a new trap and become copra. But I did look into code and found that if pet knows about polytrap it has 3 in 4 chance to dodge the trap even before magic resistance tests. [1] --Pauli (talk) 20:27, 17 December 2018 (UTC)
Nice work, Pauli. Thank you! Thidwick (talk) 21:41, 17 December 2018 (UTC)

Worth mentioning that this isn't new behavior, see: Source:NetHack_3.4.3/src/trap.c#line1705. I've definitely had this experience in 3.4.3. Slow monsters are also annoying, at least without a magic whistle. And yes, intelligent-but-weak pets will intentionally jump into a polymorph trap, just like hostile monsters. -- Qazmlpok (talk) 00:38, 18 December 2018 (UTC)
