Metamorphosis Requirements and Quick Guide(WIP)

Some Beasties require certain conditions before Metamorphosis–or otherwise have unclear directions on how to get them. I'm not an expert but this small guide aims to help new players get Beasties that are a little harder to catch!

Sprecko

Sprecko is one of two beasties that metamorph into different beasties depending on certain factors. Being one of the two beasties you team up with, you'll have this guy next to you throughout the story (or not, it's your game anyways) and you'll be able to help them metamorph through story missions. For spoiler reasons I'll block out all of the metamorph names, and leave the names of the locations needed.
Sprecko → Bongus
Interact with the Mushroom colony in the Nature Preserve, recommended you come here after you fight the ranked coach in Begonia.
TIP if you're still having trouble finding this part of the Preserve, maybe hang out with Reese some more!

Sprecko → Surgus
Explore the south part of Chroma Ocean and interact with the Mushroom colony. Reese will be there to meet you! Recommended you come here after you fight the ranked coach in Begonia.

Sprecko → Illugus
Continue the story towards Begonia and interact with the Mushroom colony, it's part of the main story so you won't miss it.

Troglum

Metamorph by going to Cordia Lake north of Begonia and interacting with the Helmet Bugs
Thank you to LEF in the comments for telling me this!

Seakit

Seakit is found in the north part of Mythwood above Begonia, throw a Shroom Ball near them to get 'em closer to the ground.
Seakit → Vultoxin
Fight and defeat 3 Petula
TIP Petula are bountiful in the chroma sea

Petula

Petula are found early on by sailing in the Chroma Sea.
TIP if you're having trouble with money to pay the boating licence, run around and research beasties (make sure you're sponsored first!)
Petula → Flowish
Fight and defeat 4 other Petula

Punkchirp

Metamorphs after making 3 relationships
Thank you to LEF in the comments for telling me this!

Jellibat

after some time spent on your team (unclear what exactly triggers this) Jellibat will have a yearning to be put into the team reserves. Once placed there check on Jellibat once again, it should have metamorphed
Thank you to LEF in the comments for telling me this!

Humflit

Humflit is found In the Nature Preserve and Mythwood, and is the second split Metamorphosis Beastie
Humflit→ Heliath
Catch and level the Red and Blue color variant to 40.
Humflit→ Lunaptra
Catch and level the Brown and White/Yellow color variant to 40.

Spoilers Ahead

From this point on, the Beasties listed are Spoiler Territory, as these specific Metamorphosis are story/postgame related. These are also significantly harder to achieve and requires a bit of patience/team building.

Platypulse

Found in the Nature Preserve early on.
Platypulse → Pladion
Boost ALL of Platypulse's DEF Stats to 5 in battle, then let it receive +3 attacks without blocking.
TIP: having a beastie with Call Out helps a lot, go to a low level area, Call Out and raise Platypulse's DEF when you can, free ball to the enemies and continue receiving. Once you're sure you've raised everything and received enough balls, end the battle and receive your Pladion!
Thank you to Razzle Dazzle for the clarification and tip in the comments!

Diggum

Diggum → Duggout
Found in the Nature Preserve.
Raise a Diggum's Spirit POW to 3 and deal 100 or more damage in an attack.

Cherrily

Cherrily → Mascurry
Found in Mythwood.
Raise a Cherrily's Body POW to 6 while their field has Rhythm.

Squimage

Squimage → Diabloceras
Found in the Chroma Sea.
Have a Squimage change it's trait while all of it's DEF stats are 3 or more.

Magpike

Magpike → Maraptor
Found in Geo City.
Have a Magpike lower it's own stamina to 0 while their POW is raised to 3 or more.

Last Words

And that's it! This is purely from my own experience, however I used this fan-made Beastiepedia for a lot of my own playthrough and I think it'll be helpful to a lot of other people so I'll link it here[beastieball.info]
If you have any extra info please comment it, or if you have any questions feel free to ask! Thank you for reading!

Niche tip that came in helpful for me, if you find a Raremorph Humflit, it will metamorph into Heliath, UNLESS you metamorph it in Alto Alps, then it will transform into its Lunaptra.

[WackadoodleGrimm]

I have not tested Magpike's yet, that info came from a the fanmade beastiepedia listed at the end--if you're having more trouble I suggest the beastieball Discord! The creators have an official Discord and I've recieved a lot of help there :)

[WackadoodleGrimm]

I've been able to do the Cherrily one once before, it took me I think 2 times? Just get a beastie with Cheer (or some other stat boosting play) then after it's stats are raised set up the rhythm, you do not need to raise the stats while the rhythm is up--Just have it's stats raised to the correct amount when rhythm is up! I suggest doing it in a low level area for ease

[redwoodskyclone]

I know this is all new but I haven't been able to get the Magpike or Cherrily metamorphs from using the listed methods. The Cherrily one might be especially hard cuz it's difficult to raise power enough times before rhythm runs out.

Also Punkchirp -> Magpike is it forming three relationships. Jellibat -> Froofulks is fulfilling its yearning to put it into reserves (once you do this, checking reserves will show that it metamorphed). Unknown what triggers the yearning, if not just spending a while on your team.

[LEF]

Troglum also has a special metamorph method. You have to go to the big island in the middle of Cordia Lake in Mythwood. There is a Rowdy Varkabond (the evolution) you have to defeat first. Then you can just interact with one of the helmet bug thingies to trigger the metamorph.

[WackadoodleGrimm]

Each beastie has it's own requirement to tame them, if you've played up until you meet Reese and unlock research+beastiepedia, you can look in it to see each beastie and it's requirements for taming. It may be something like "move your beasties on the court 3+ times", once you do that you'll see a mini "cutscene" that'll show you've completed it's requirement. Usually you need to completely finish a beasties research before knowing it's requirement to join your team. Also make sure you have a jersey on hand!

How can I tame beasties? I'm still not clear on how to tame them.

Found it!! Thank you!!

Duggout is only 2 rooms away from the rowdy Bongus room, the picture for Sprecko's first Metamorph actually shows the room you need! Go to the room with a small lake, there should be a ledge you can hop on--happy hunting!
