Greetings again, to whoever is here now. I have decided to bring back this instead of making a new post about it, I have returned with an update and another ask for help for finishing these entries.
First, I apologise for my behavior earlier about this topic, I was not being very specific and I was very frustrated at the lack of progress. I really should not have taken it out on the people who were trying to offer assistance.
I will start with good news, after my break from this nightmare I have got one of the entries! Instead of waiting for a jungle turtle to spawn, I got 5 regular turtles and created a turtle statue, this statue can spawn fake jungle turtles which still count towards the entry. Now only one remains!
I have tried a few methods for getting a grebe to spawn, to the best of my knowledge I must be in a desert biome in a town, and have water for the grebe to spawn in. However this knowledge alone has not given me a grebe spawn.
Here are some screenshots of zones I have tried/am trying to use to spawn one.
This is my first test for getting a grebe spawn, it is set in the 'fake surface' of the GFB world's cavern layer, note the lack of background walls. I set up dams and flooded most spawnable pieces of land here, making sure it was close to a desert town to maximise critter spawns.
I tried using a duck statue to spawn one, similar to the turtle statue, but it only spawns regular and mallard ducks. I have to get this one to spawn naturally.
One piece of information that I have been using to tell if I am getting close is the appearance of pupfish, pupfish are another desert critter which spawn in water, but apparently at a higher ratio than grebe or under another unknown condition I may have met that I have not satisfied for the grebe.
I know that this area can spawn critters, but after a long time of waiting here, catching/killing critters to allow others to spawn, no grebe has appeared.
After the failure of my first attempt to spawn a grebe, my main theory for why it failed is because I was not at the surface. So I cut out the desert from my surface and purified it all using a clentaminator (later shimmered into terraformer) that I migrated from another world. Allow terraformer in DDU/GFB after moon lord please.
But anyway, after cleaning it all up, I did the same for flooding and setting up a town here, standing in the middle at the pyramid caused nearly all of the spawns to be critters, most being even more pupfish, I own 93 pupfish and have killed another 256 in my boredom. This leads me to believe that a grebe spawn is achievable in this area, but I am missing an important step to spawning one.
I have a theory on how to spawn one, which I have not tested yet as of writing this: While researching turtle and jungle turtle spawns, I read that
regular turtles spawn only in water that is a certain depth level (2+ deep I believe?) and if the tile beneath is mowed or regular grass. Perhaps grebe need a specific tile below the water to spawn? Though currently the block under the water is sand and I do not imagine a different tile possibly being it, though it is worth considering. Maybe grebe instead need lilypads or desert cattails nearby to spawn, similar to dragonflies?
If anyone has an idea on getting one to spawn, a theory on what I could do to make one spawn, a record or a getfixedboi/don'tdigup world with the grebe entry or any other help please let me know.
I am incredibly grateful for Kazzymodus testing if they spawn at all, and confirming it
is possible, however following all that I know before and have been told this grebe still eludes me.
Thanks for reading.
