If your fairly built up you can grab with a skiff bring it to your base.(THIS STEP IS OPTIONAL) get a friend to grapple it with a good amount of stuff on u so it can't move and shoot it in the head with the M.S.C.M attachment on a mek. This is for late game and the mek cannon know them out fast than a cannon if you play boosted would recommend.
It's a bit silly that kibble tames it a lot better than rocks or sulfur because even in the dossier it says that it lives off of absorbing nearby rocks and minerals. So mabey they should make it so you have to feed them a rare mineral like obsidian what if they made it so you could tame one fast and with high effectiveness by giving one a few hundred or few thousand obsidian . or what if there kibble was made out of a combination of ores and minerals .
