Teeny Ships (タイニーシップ, Tainī Shippu?, lit. "Tiny Ship") are smaller, simpler versions of the Gummi Ship found in Kingdom Hearts II and Kingdom Hearts III. Teeny Ships attack alongside the main Gummi Ship or deflect enemy attacks.
In Kingdom Hearts III, one Teeny Ship is unlocked upon reaching Gummi Level 12, while the second is unlocked at Gummi Level 24.
Teeny Ships are unlocked alongside Blueprints, although not all Blueprints have Teeny Ships.
