I'll be looking for a Tangela in the platinum safari zone soon and although I technically know how to catch Pokemon in there I don't know when I should use bait and when I should throw a rock. If anyone knows the best combination of bait/ball/rock then please, share.
Okay first of all I'll go through what each thing does.
Most players when in the safari have to just hope on luck when trying to catch Pokémon. The only way that makes it more likely without being too risky is to throw one rock and then immediately throw a Safari Ball.
Hope I helped :)
